+# Purpose:
+# Bootstrap resamples an alignment in PHYLIP sequential format <bootstraps> times.
+# Bootstrapping is not done randomly but according to a BSP (bootstrap 
+# positions) file.
+# The BSP file can be created with the Perl program "bootstrap_cz.pl"
+# in mode 0.
+# This prgram has the same functionality as "bootstrap_cz.pl" in mode 1.
+# Sequence names are normalized to LENGTH_OF_NAME characters.
+# The output alignment is in PHYLIP's sequential or interleaved format.
+# (These two are the same in this case, since all the seqs will be one
+# line in length (no returns in seq).)
+# 
+# Usage: bootstrap_cz <bootstraps> <alignment infile> <BSP file> <outfile>
+#        [number of processors]

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                          675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	Appendix: How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+           It is highly recommended that you read this paper before
+           installing and/or using RIO. (Included in the RIO 
+           distribution as PDF: "RIO.pdf".)
+           
+
+Preconditions: A Unix system, Java 1.2 or higher, Perl, gcc or cc,  
+               ... and some experience with Perl and Unix.
+
+
+
+1. Compilation
+______________
+
+
+This describes how to compile the various components of RIO.
+
+
+  "gunzip RIO1.x.tar.gz"
+  
+  "tar -xvf RIO1.x.tar"
+
+
+
+
+in directory "RIO1.x/C":
+
+ "make"
+
+
+
+in directory "RIO1.x/hmmer" (version of HMMER is "2.2g"):
+
+(if you already have a local copy of HMMER 2.2g installed, this step
+is not necessary, but in this case you need to change variables "$HMMALIGN",
+"$HMMSEARCH", "$HMMBUILD", "$HMMFETCH", and "$SFE" to point to the 
+corresponding HMMER programs)
+
+ "./configure"
+
+ "make"
+
+
+
+in directory "RIO1.x/java" (requires JDK 1.2 or greater):
+
+ "javac forester/tools/*java"
+
+ "javac ATVapp.java"
+
+
+
+
+in directory "RIO1.x/puzzle_dqo":
+
+ "./configure"
+
+ "make"
+
+
+
+in directory "RIO1.x/puzzle_mod":
+
+ "./configure"
+
+ "make"
+
+
+
+in directory "RIO1.x/phylip_mod/src":
+ 
+  "make install"
+
+
+
+
+2. Setting the variables in "RIO1.x/perl/rio_module.pm"
+_______________________________________________________
+
+
+Most global variables used in "RIO1.x/perl/rio.pl" are set in
+the perl module "RIO1.x/perl/rio_module.pm".
+This module pretty much "controls everything".
+
+It is necessary to set the variables which point to:
+
+-- the rio directory itself: $PATH_TO_FORESTER
+
+   (example: $PATH_TO_FORESTER = "/home/czmasek/linux/RIO1.1/";)
+
+
+-- your Java virtual machine: $JAVA
+
+   (example: $JAVA = "/home/czmasek/linux/j2sdk1.4.0/bin/java";) 
+
+
+-- a directory where temporary files can be created: $TEMP_DIR_DEFAULT 
+
+
+
+   Example:
+   Now that $PATH_TO_FORESTER, $JAVA, $TEMP_DIR_DEFAULT are set,
+   it is posssible to run rio.pl based on the example precalculated distances
+   in "/example_data/":
+
+     % RIO1.1/perl/rio.pl 1 A=aconitase Q=RIO1.1/LEU2_HAEIN N=QUERY_HAEIN O=out0 p I
+
+   To use RIO to analyze your protein sequences, please continue setting
+   variables and preparing data......
+
+
+
+-- your local copy of the Pfam database (see http://pfam.wustl.edu/)
+   (if only precalculated distances are being used, these variables do not
+    matter):
+
+   $PFAM_FULL_DIRECTORY -- the directory containing the "full" alignments
+                           (Pfam-A.full) see below (3.)
+
+   $PFAM_SEED_DIRECTORY -- the directory containing the "seed" alignments
+                           (Pfam-A.seed) see below (3.)
+
+   $PFAM_HMM_DB         -- the Pfam HMM library file (Pfam_ls)
+                           see below (3.)
+
+
+-- $TREMBL_ACDEOS_FILE and $SWISSPROT_ACDEOS_FILE: see below (4. and 5.).
+
+
+-- list of species (SWISS-PROT codes) which can be analyzed: $SPECIES_NAMES_FILE
+   (for most purposes $PATH_TO_FORESTER."data/species/tree_of_life_bin_1-4_species_list"
+   should be sufficient, hence this variable does not necessarly need to be changed)
+
+
+-- a default species tree in NHX format: $SPECIES_TREE_FILE_DEFAULT
+   (for most purposes $PATH_TO_FORESTER."data/species/tree_of_life_bin_1-4.nhx"
+   should be sufficient, hence this variable does not necessarly need to be changed)
+
+
+-- Only if precalculated distances are being used:
+   $MATRIX_FOR_PWD, $RIO_PWD_DIRECTORY, $RIO_BSP_DIRECTORY,
+   $RIO_NBD_DIRECTORY, $RIO_ALN_DIRECTORY, and $RIO_HMM_DIRECTORY:
+   please see below (6.) 
+
+
+
+
+
+
+IMPORTANT:  Need to redo steps 3., 4., 5., and 6. if species
+            in the master species tree and/or the species list
+            are added and/or changed or if a new version of Pfam is used!!
+
+
+
+
+
+3. Downloading and processing of Pfam
+_____________________________________
+
+
+
+Please note: Even if you already have a local copy of the
+Pfam database, you still need to perform steps c. through k. 
+
+a. download 
+   - "Pfam_ls" (PFAM HMM library, glocal alignment models)
+   - "Pfam-A.full" (full alignments of the curated families)
+   - "Pfam-A.seed" (seed alignments of the curated families)
+     [and ideally "prior.tar.gz"]
+   from http://pfam.wustl.edu/ or ftp.genetics.wustl.edu/pub/eddy/pfam-x/
+
+b. "gunzip" and "tar -xvf" these downloaded files, if necessary
+
+c. create a new directory named "Full" and move "Pfam-A.full" into it
+
+d. in directory "Full" execute "RIO1.x/perl/pfam2slx.pl Pfam-A.full"
+
+e. set variable $PFAM_FULL_DIRECTORY in "RIO1.x/perl/rio_module.pm"
+   to point to this "Full" directory
+
+f. create a new directory named "Seed" and move "Pfam-A.seed" into it
+
+g. in directory "Seed" execute "RIO1.x/perl/pfam2slx.pl Pfam-A.seed"
+
+h. set variable $PFAM_SEED_DIRECTORY in "RIO1.x/perl/rio_module.pm"
+   to point to this "Seed" directory
+
+i. execute "RIO1.x/hmmer/binaries/hmmindex Pfam_ls" (in same
+   directory as "Pfam_ls") resulting in "Pfam_ls.ssi"
+
+j. set environment variable HMMERDB to point to the directory where
+   "Pfam_ls" and "Pfam_ls.ssi" reside
+   (for example "setenv HMMERDB /home/czmasek/PFAM7.3/")
+
+k. set variable $PFAM_HMM_DB in "RIO1.x/perl/rio_module.pm"
+   to point to the "Pfam_ls" file
+   (for example $PFAM_HMM_DB = "/home/czmasek/PFAM7.3/Pfam_ls";)
+
+
+
+
+4. Extraction of ID, DE, and species from a SWISS-PROT sprot.dat file
+_____________________________________________________________________
+
+
+This creates the file from which RIO will get the sequence descriptions for
+sequences from SWISS-PROT.
+(RIO1.x/data/ does not contain an example for this, since SWISS-PROT is
+copyrighted.)
+
+
+a. download SWISS-PROT "sprotXX.dat" from
+   "ftp://ca.expasy.org/databases/swiss-prot/release/"
+
+b. "extractSWISS-PROT.pl <infile> <outfile> [species list]"
+
+    ("extractSWISS-PROT.pl" is in "RIO1.x/perl")
+
+    example:
+    "extractSWISS-PROT.pl sprot40.dat sp40_ACDEOS RIO1.x/data/species/tree_of_life_bin_1-4_species_list"
+
+c. the output file should be placed in "RIO1.x/data" and the
+   variable $SWISSPROT_ACDEOS_FILE in "RIO1.x/perl/rio_module.pm" should point
+   to this output.
+
+
+
+
+5. Extraction of AC, DE, and species from a TrEMBL trembl.dat file
+__________________________________________________________________
+
+
+This creates the file from which RIO will get the sequence descriptions for
+sequences from TrEMBL.
+(RIO1.x/data/ already contains an example: "trembl20_ACDEOS_1-4")
+
+a. download TrEMBL "trembl.dat.gz" from
+   "ftp://ca.expasy.org/databases/sp_tr_nrdb/"
+
+b. "gunzip trembl.dat.gz"
+
+c. "extractTrembl.pl <infile> <outfile> [species list]"
+
+    ("extractTrembl.pl" is in "RIO1.x/perl")
+
+    example:
+    "extractTrembl.pl trembl.dat trembl17.7_ACDEOS_1-4 RIO1.x/data/species/tree_of_life_bin_1-4_species_list"
+
+d. the output file should be placed in "RIO1.x/data/" and the
+   variable $TREMBL_ACDEOS_FILE in "RIO1.x/perl/rio_module.pm" should point
+   to this output.
+
+
+
+Now, you could go to directly to 7. to run the examples......
+
+
+
+6. Precalculation of pairwise distances (optional): pfam2pwd.pl
+_______________________________________________________________
+
+
+This step is of course only necessary if you want to use RIO on
+precalculated pairwise distances. The precalculation is time consuming
+(range of one or two weeks on ten processors).
+It is best to run it on a few machines, dividing up the input data.
+
+The program to do this, is "RIO1.x/perl/pfam2pwd.pl".
+
+Please note: "pfam2pwd.pl" creates a logfile in the same directory
+             where is places the pairwise distance output ($MY_RIO_PWD_DIRECTORY).
+              
+
+
+The following variables in "RIO1.x/perl/pfam2pwd.pl" need to be set
+("pfam2pwd.pl" gets most of its information from "rio_module.pm"):
+
+
+"$MY_PFAM_FULL_DIRECTORY":
+  This is the directory where the Pfam full alignments reside, processed
+  as described in 3.a to 3.d.
+
+
+
+"$ALGNS_TO_USE_LIST_FILE":
+  If left empty, all alignments in $MY_PFAM_FULL_DIRECTORY are being
+  used the calculate pairwise distances from.
+  If this points to a file listing names of Pfam alignments,
+  only those listed are being used.
+  The file can either be a simple new-line deliminated list, or can have
+  the same format as the "Summary of changes" list
+  ("FI   PF03214 RGP   NEW  SEED HMM_ls HMM_fs FULL DESC")
+  which is part of the Pfam distribution.
+  One purpose of this is to use the list of "too large" alignments
+  in the logfile produced by "pfam2pwd.pl" to run "pfam2pwd.pl" with 
+  a smaller species list (as can be set with "$MY_SPECIES_NAMES_FILE")
+  on large alignments.
+
+  
+
+"$MY_SPECIES_NAMES_FILE" -- Dealing with too large alignments:
+
+  This is most important. It determines the species whose sequences 
+  are being used (sequences from species not listed in $MY_SPECIES_NAMES_FILE
+  are ignored). Normally, one would use the same list as RIO uses
+  ($SPECIES_NAMES_FILE in "rio_module.pm"):
+
+  my $MY_SPECIES_NAMES_FILE = $SPECIES_NAMES_FILE;
+
+  For certain large families (such as protein kinases, one must use
+  a species file which contains less species in order to be able to finish
+  the calculations in reasonable time:
+
+  my $MY_SPECIES_NAMES_FILE = $PATH_TO_FORESTER."data/tree_of_life_bin_1-4_species_list_NO_RAT_RABBIT_MONKEYS_APES_SHEEP_GOAT_HAMSTER
+  
+  An additional way to reduce the number of sequences in an alignment is
+  to only use sequences originating from SWISS-PROT. This is done by
+  placing the following line of code into pfam2pwd.pl:
+
+  $TREMBL_ACDEOS_FILE = $PATH_TO_FORESTER."data/NO_TREMBL"; 
+
+
+
+"$MY_RIO_PWD_DIRECTORY",
+"$MY_RIO_BSP_DIRECTORY",
+"$MY_RIO_NBD_DIRECTORY",
+"$MY_RIO_ALN_DIRECTORY",
+"$MY_RIO_HMM_DIRECTORY":
+  These determine where to place the output.
+  After all the data has been calculated, the corresponding variables
+  in RIO1.x/perl/rio_module.pm ("$RIO_PWD_DIRECTORY", etc.) need to be set
+  so that they point to the appropriate values. Having different variables
+  allows to precalculate distances and at the same time use RIO on
+  previously precalculated distances.
+
+
+
+"$MY_TEMP_DIR":
+  A directory to create temporary files in.
+
+
+
+"$MIN_SEQS":
+  Alignments in which the number of sequences after pruning (determined
+  by "$MY_SPECIES_NAMES_FILE") is lower than $MIN_SEQS, are ignored
+  (no calculation of pwds).
+
+
+
+"$MAX_SEQS":
+  Alignments in which the number of sequences after pruning (determined
+  by "$MY_SPECIES_NAMES_FILE") is greater than $MAX_SEQS, are ignored
+  (no calculation of pwds).
+
+
+
+"$MY_SEED":
+  Seed for the random number generator for bootstrapping (must be 4n+1).
+
+
+
+"$MY_MATRIX":
+  This is used to choose the model to be used for the (ML)
+  distance calculation:
+  0 = JTT
+  2 = BLOSUM 62
+  3 = mtREV24
+  5 = VT
+  6 = WAG
+  PAM otherwise
+  After all the data has been calculated, variable "$MATRIX_FOR_PWD"
+  in RIO1.x/perl/rio_module.pm needs to be set to the same value.
+
+
+
+Once pairwise distances are calculated, the following variables in
+"rio_module.pm" need to be set accordingly:
+$MATRIX_FOR_PWD     : corresponds to $MY_MATRIX in pfam2pwd.pl
+$RIO_PWD_DIRECTORY  : corresponds to $MY_RIO_PWD_DIRECTORY in pfam2pwd.pl
+$RIO_BSP_DIRECTORY  : corresponds to $MY_RIO_BSP_DIRECTORY in pfam2pwd.pl
+$RIO_NBD_DIRECTORY  : corresponds to $MY_RIO_NBD_DIRECTORY in pfam2pwd.pl
+$RIO_ALN_DIRECTORY  : corresponds to $MY_RIO_ALN_DIRECTORY in pfam2pwd.pl
+$RIO_HMM_DIRECTORY  : corresponds to $MY_RIO_HMM_DIRECTORY in pfam2pwd.pl
+...of course, if Pfam has been updated, the corresponding variables in rio_module.pm
+($PFAM_FULL_DIRECTORY, etc.) need to be updated, too.
+
+
+
+
+
+
+IMPORTANT:  Need to redo steps 3., 4., 5., and 6. if species
+            in the master species tree and/or the species list
+            are added and/or changed or if a new version of Pfam is used!
+
+
+
+
+7. Example of a phylogenomic analysis using "rio.pl"
+____________________________________________________
+
+
+Without using precalculated distances (for this, all the variables above
+need to point to the correct loctions, in particular to your local and processed
+Pfam database): 
+
+  % RIO1.1/perl/rio.pl 3 A=/path/to/my/pfam/Full/aconitase H=aconitase Q=RIO1.1/LEU2_HAEIN N=QUERY_HAEIN O=out3 p I C E
+
+
+
+Without using precalculated distances (for this, all the variables above
+need to point to the correct loctions, in particular to your local and processed
+Pfam database) using a query sequence which is already in the alignment:
+
+  % RIO1.1/perl/rio.pl 4 A=/path/to/my/pfam/Full/aconitase N=LEU2_LACLA/5-449 O=out4 p I C E
+
+
+
+Using the example precalculated distances in "/example_data/"
+($RIO_PWD_DIRECTORY, etc. need to point to $PATH_TO_FORESTER."example_data/"):
+
+  % RIO1.1/perl/rio.pl 1 A=aconitase Q=RIO1.1/LEU2_HAEIN N=QUERY_HAEIN O=out1 p I C E
+
+
+
+Using a query sequence which is already in the precalculated distances in "/example_data/"

+HMMER - profile hidden Markov models for biological sequence analysis
+Version 2.2 (August 2001)
+Copyright (C) 1992-2001 Washington University School of Medicine
+------------------------------------------------------------------
+
+o About this software...
+   HMMER is an implementation of profile HMM methods for
+   sensitive database searches using multiple sequence alignments as queries.
+
+   Basically, you give HMMER a multiple sequence alignment as input;
+   it builds a statistical model called a "hidden Markov model"
+   which you can then use as a query into a sequence database
+   to find (and/or align) additional homologues of the sequence family.
+
+o Getting HMMER
+   WWW home:       http://hmmer.wustl.edu/
+   Distribution:   ftp://ftp.genetics.wustl.edu/pub/eddy/hmmer/

+Brief installation instructions for HMMER 2.2
+SRE, Sun Aug  5 16:22:52 2001
+------------------------------------------
+
+For a source distribution (hmmer-2.2.tar.gz):
+
+    uncompress hmmer-2.2.tar.gz  Uncompresses the archive.
+    tar xf hmmer-2.2.tar         Unpacks the archive. (makes a new directory, hmmer-2.2)
+    cd hmmer-2.2                 Moves into the distribution toplevel directory.
+    ./configure                  Configures the software for your system.
+    make                         Builds the binaries. 
+    make check                   Runs the test suite to test the new binaries.
+    make install                 Installs the software. (You may need to be root.)
+
+    It should build cleanly on just about any UNIX machine.
+
+For a binary distribution (hmmer-2.2.bin.<platform>-<os>.tar.gz),
+for example, the sun-solaris distro:
+
+    uncompress hmmer-2.2.bin.sun-solaris.tar.Z
+    tar xf hmmer-2.2.bin.sun-solaris.tar
+    cd hmmer-2.2
+    ./configure
+    make install
+
+    Note that "make" and "make check" aren't necessary, since you
+    have a precompiled distribution.
+
+    If your machine doesn't have a C compiler, the ./configure will
+    fail, and you won't be able to do a "make install". This is
+    an artifact of the way I have the configure script built.
+    If this happens, just copy the man pages and binaries whereever
+    you want them, for instance:
+
+    cp Man/*      /usr/local/man/man1/
+    cp binaries/* /usr/local/bin/
+
+    HMMER doesn't depend on any external data files, so the installation is
+    simple - the binaries are free standing, and you can install
+    them anywhere you like.
+
+For more detail, see the Installation chapter in the HMMER User's
+Guide.

+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	Appendix: How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+HMMER 2.2 release notes
+http://hmmer.wustl.edu/
+SRE, Fri May  4 13:00:33 2001
+---------------------------------------------------------------
+
+As it has been more than 2 years since the last HMMER release, this is
+unlikely to be a comprehensive list of changes.
+
+HMMER is now maintained under CVS. Anonymous read-only access to the
+development code is permitted. To download the current snapshot:
+    > setenv CVSROOT :pserver:anonymous@skynet.wustl.edu:/repository/sre
+    > cvs login
+      [password is "anonymous"]
+    > cvs checkout hmmer

+
+The following programs were added to the distribution:
+
+   - The program "afetch" can fetch an alignment from
+     a Stockholm format multiple alignment database (e.g. Pfam).
+     "afetch --index" creates the index files for such
+     a database.
+
+   - The program "shuffle" makes "randomized" sequences.
+     It supports a variety of sequence randomization methods,
+     including an implementation of Altschul/Erickson's
+     shuffling-while-preserving-digram-composition algorithm.
+
+   - The program "sindex" creates SSI indices from sequence
+     files, that "sfetch" can use to rapidly retrieve sequences
+     from databases. Previously, index files were constructed
+     with Perl scripts that were not supported as part of the
+     HMMER distribution.
+
+The following features were added:
+
+   - hmmsearch and hmmpfam can now use Pfam GA, TC, NC cutoffs,
+     if these have been picked up in the HMM file (by hmmbuild). 
+     See the --cut_ga, --cut_tc, and --cut_nc options.
+
+   - "Stockholm format" alignments are supported, and have replaced
+     SELEX format as the default alignment format. Stockholm format
+     is the alignment format agreed upon by the Pfam Consortium,
+     providing extensible markup and annotation capabilities. HMMER
+     writes Stockholm format alignments by default. The program
+     sreformat can reformat alignments to other formats, including
+     Clustal and GCG MSF formats.
+
+   - To improve robustness, particularly in high-throughput annotation
+     pipelines, all programs now accept an option --informat <s>,
+     where <s> is the name of a sequence file format (FASTA, for
+     example). The format autodetection code that is used by default
+     is almost always right, and is very helpful in interactive use
+     (HMMER reads almost anything without you worrying much about
+     format issues). --informat bypasses the autodetector, asserts
+     a particular format, and decreases the likelihood that HMMER
+     misparses a sequence file.
+     
+   - new options:
+     hmmpfam --acc reports HMM accession numbers instead of
+     HMM names in output files. [Pfam infrastructure]
+
+     sreformat --nogap, when reformatting an alignment,
+     removes all columns containing any gap symbols; useful
+     as a prefilter for phylogenetic analysis.
+
+   - The real software version of HMMER is logged into
+     the HMMER2.0 line of ASCII save files, for better
+     version control (e.g. bug tracking, but there are
+     no bugs in HMMER).
+
+   - GCG MSF format reading/writing is now much more robust,
+     thanks to assistance from Steve Smith at GCG.
+
+   - The PVM implementation of hmmcalibrate is now
+     parallelized in a finer grained fashion; single models
+     can be accelerated. (The previous version parallelized
+     by assigning models to processors, so could not
+     accelerate a single model calibration.)
+
+   - hmmemit can now take HMM libraries as input, not just
+     a single HMM at a time - useful for instance for producing
+     "consensus sequences" for every model in Pfam with one
+     command.
+ 
+The following changes may affect HMMER-compatible software:
+
+   - The name of the sequence retrieval program "getseq" was
+     changed to "sfetch" in this release. The name "getseq"
+     clashes with a Genetics Computer Group package program
+     of similar functionality.
+
+   - The output format for the headers of hmmsearch and hmmpfam 
+     were changed. The accessions and descriptions of query
+     HMMs or sequences, respectively, are reported on separate 
+     lines. An option ("--compat") is provided for reverting
+     to the previous format, if you don't want to rewrite your
+     parser(s) right away.
+
+   - hmmpfam now calculates E-values based on the actual 
+     number of HMMs in the database that is searched, unless
+     overridden with the -Z option from the command line.
+     It used to use Z=59021 semi-arbitrarily to make results
+     jibe with a typical hmmsearch, but this just confused
+     people more than it helped. hmmpfam E-values will therefore
+     become more significant in this release by about 37x,
+     for a typical Pfam search (59021/1600 = 37).
+
+The following major bugs were fixed:
+    [none]
+
+The following minor bugs were fixed:
+   - more argument casting to silence compiler warnings
+     [M. Regelson, Paracel ]
+
+   - a potential reentrancy problem with setting the
+     alphabet type in the threads version was 
+     fixed, but this problem is unlikely to have ever affected
+     anyone. [M. Sievers, Paracel].
+
+   - fixed a bug where hmmbuild on Solaris machines would crash 
+     when presented with an alignment with an #=ID line.
+     Same bug caused a crash when building a model from a single
+     sequence FASTA file [A. Bateman, Sanger]
+
+   - The configure script was modified to deal better with
+     different vendor's implementations of pthreads, in response
+     to a DEC Digital UNIX compilation problem [W. Pearson,
+     U. Virginia]
+
+   - Automatic sequence file format detection was slightly
+     improved, fixing a bug in detecting GCG-reformatted
+     Swissprot files [reported by J. Holzwarth]
+
+   - hmmpfam-pvm and hmmindex had a bad interaction if an HMM file had
+     accession numbers as well as names (e.g., Pfam). The phenotype was
+     that hmmpfam-pvm would search each model twice: once for its name,
+     and once for its accession. hmmindex now uses a new 
+     indexing scheme (SSI, replacing GSI). [multiple reports;
+     often manifested as a failure of the StL Pfam server to
+     install, because of an hmmindex --one2one option in the Makefile; this was 
+     a local hack, never distributed in HMMER].
+
+   - a rare floating exception bug in ExtremeValueP() was fixed;
+     range-checking protections in the function were in error, and
+     a range error in a log() calculation appeared on
+     Digital Unix platforms for a *very* tiny set of scores
+     for any given mu, lambda.
+
+   - The default null2 score correction was applied in 
+     a way that was justifiable, but differed between per-seq
+     and per-domain scores; thus per-domain scores did not
+     necessarily add up to per-seq scores. In certain cases
+     this produced counterintuitive results. null2 is now
+     applied in a way that is still justifiable, and also 
+     consistent; per-domain scores add up to the per-seq score.
+     [first reported by David Kerk]
+    
+   - --domE and --domT did not work correctly in hmmpfam, because 
+     the code assumed that E-values are monotonic with score.
+     In some cases, this could cause HMMER to fail to report some 
+     significant domains. [Christiane VanSchlun, GCG]
+
+The following obscure bugs were fixed (i.e., there were no reports of
+anyone but me detecting these bugs):
+
+  - sreformat no longer core dumps when reformatting a
+    single sequence to an alignment format.
+
+  - Banner() was printing a line to stdout instead of its
+    file handle... but Banner is always called w/ stdout as
+    its filehandle in the current implementation. 
+    [M. Regelson, Paracel] 
+
+  - .gz file reading is only supported on POSIX OS's. A compile
+    time define, SRE_STRICT_ANSI, may be defined to allow compiling
+    on ANSI compliant but non-POSIX operating systems.
+
+  - Several problems with robustness w.r.t. unexpected
+    combinations of command line options were detected by 
+    GCG quality control testing. [Christiane VanSchlun]
+
+(At least) the following projects remain incomplete:
+
+  - Ian Holmes' posterior probability routines (POSTAL) are
+    partially assimilated; see postprob.c, display.c
+
+  - CPU times can now be reported for serial, threaded,
+    and PVM executions; this is only supported by hmmcalibrate
+    right now. 
+
+  - Mixture Dirichlet priors now include some ongoing work
+    in collaboration with Michael Asman and Erik Sonnhammer
+    in Stockholm; also #=GC X-PRM, X-PRT, X-PRI support in
+    hmmbuild/Stockholm annotation.

+.SH NAME
+.TP 
+hmmalign - align sequences to an HMM profile
+
+.SH SYNOPSIS
+.B hmmalign
+.I [options]
+.I hmmfile
+.I seqfile
+
+.SH DESCRIPTION
+
+.B hmmalign
+reads an HMM file from
+.I hmmfile
+and a set of sequences from 
+.I seqfile,
+aligns the sequences to the profile HMM, 
+and outputs a multiple sequence alignment.
+
+.PP
+.I seqfile 
+may be in any unaligned or aligned file format
+accepted by HMMER. If it is in a multiple alignment format
+(e.g. Stockholm, MSF, SELEX, ClustalW), the existing alignment
+is ignored (i.e., the sequences are read as if they were
+unaligned - hmmalign will align them the way it wants).
+
+.SH OPTIONS
+
+.TP
+.B -h
+Print brief help; includes version number and summary of
+all options, including expert options.
+
+.TP
+.B -m
+Include in the alignment only those symbols aligned to match states.
+Do not show symbols assigned to insert states. 
+
+.TP 
+.BI -o " <f>"
+Save alignment to file
+.I <f>
+instead of to standard output.
+
+.TP
+.B -q
+quiet; suppress all output except the alignment itself.
+Useful for piping or redirecting the output.
+
+.SH EXPERT OPTIONS
+
+.TP
+.BI --informat " <s>"
+Assert that the input 
+.I seqfile
+is in format
+.I <s>;
+do not run Babelfish format autodection. This increases
+the reliability of the program somewhat, because 
+the Babelfish can make mistakes; particularly
+recommended for unattended, high-throughput runs
+of HMMER. Valid format strings include FASTA,
+GENBANK, EMBL, GCG, PIR, STOCKHOLM, SELEX, MSF,
+CLUSTAL, and PHYLIP. See the User's Guide for a complete
+list.
+
+.TP
+.BI --mapali " <f>"
+Reads an alignment from file 
+.I <f>
+and aligns it as a single object to the HMM; e.g. the alignment in 
+.I <f> 
+is held fixed. 
+This allows you to align sequences to a model with 
+.B hmmalign
+and view them in the context of an existing trusted
+multiple alignment. 
+The alignment to the alignment is defined by a "map" kept
+in the HMM, and so is fast and guaranteed to be consistent
+with the way the HMM was constructed from the alignment.
+The alignment in the file
+.I <f>

+option.
+
+.TP 
+.BI --withali " <f>"
+Reads an alignment from file 
+.I <f>
+and aligns it as a single object to the HMM; e.g. the alignment in 
+.I <f> 
+is held fixed.
+This allows you to align sequences to a model with 
+.B hmmalign
+and view them in the context of an existing trusted
+multiple alignment. The alignment to the alignment is
+done with a heuristic (nonoptimal) dynamic programming procedure,
+which may be somewhat slow and is not guaranteed to
+be completely consistent with the way the HMM was
+constructed (though it should be quite close).
+However, any alignment can be used, not just the alignment that
+the HMM was built from. Compare the
+.B --mapali 
+option.

+.SH NAME
+.TP 
+hmmbuild - build a profile HMM from an alignment
+
+.SH SYNOPSIS
+.B hmmbuild
+.I [options]
+.I hmmfile
+.I alignfile
+
+.SH DESCRIPTION
+
+.B hmmbuild 
+reads a multiple sequence alignment file 
+.I alignfile
+, builds a new profile HMM, and saves the HMM in 
+.I hmmfile.
+
+.PP
+.I alignfile
+may be in ClustalW, GCG MSF, SELEX, Stockholm, or aligned FASTA
+alignment format. The format is automatically detected.
+
+.PP
+By default, the model is configured to find one or more
+nonoverlapping alignments to the complete model: multiple
+global alignments with respect to the model, and local with
+respect to the sequence.
+This
+is analogous to the behavior of the 
+.B hmmls 
+program of HMMER 1. 
+To configure the model for multiple 
+.I local 
+alignments
+with respect to the model and local with respect to
+the sequence,
+a la the old program
+.B hmmfs,
+use the
+.B -f 
+(fragment) option. More rarely, you may want to 
+configure the model for a single
+global alignment (global with respect to both
+model and sequence), using the 
+.B -g
+option;
+or to configure the model for a single local/local alignment
+(a la standard Smith/Waterman, or the old
+.B hmmsw
+program), use the
+.B -s 
+option.
+
+.SH OPTIONS
+
+.TP 
+.B -f
+Configure the model for finding multiple domains per sequence,
+where each domain can be a local (fragmentary) alignment. This
+is analogous to the old
+.B hmmfs
+program of HMMER 1.
+
+.TP
+.B -g
+Configure the model for finding a single global alignment to
+a target sequence, analogous to
+the old
+.B hmms
+program of HMMER 1.
+
+.TP
+.B -h
+Print brief help; includes version number and summary of
+all options, including expert options.
+
+.TP
+.BI -n " <s>" 
+Name this HMM
+.I <s>. 
+.I <s>
+can be any string of non-whitespace characters (e.g. one "word").
+There is no length limit (at least not one imposed by HMMER;
+your shell will complain about command line lengths first).
+
+.TP
+.BI -o " <f>"
+Re-save the starting alignment to 
+.I <f>,
+in Stockholm format.
+The columns which were assigned to match states will be
+marked with x's in an #=RF annotation line. 
+If either the
+.B --hand 
+or 
+.B --fast
+construction options were chosen, the alignment may have
+been slightly altered to be compatible with Plan 7 transitions,
+so saving the final alignment and comparing to the 
+starting alignment can let you view these alterations.
+See the User's Guide for more information on this arcane
+side effect.
+
+.TP
+.B -s 
+Configure the model for finding a single local alignment per
+target sequence. This is analogous to the standard Smith/Waterman
+algorithm or the 
+.B hmmsw
+program of HMMER 1. 
+
+.TP
+.B -A
+Append this model to an existing
+.I hmmfile
+rather than creating 
+.I hmmfile.
+Useful for building HMM libraries (like Pfam).
+
+.TP 
+.B -F
+Force overwriting of an existing 
+.I hmmfile.
+Otherwise HMMER will refuse to clobber your existing HMM files,
+for safety's sake.
+
+.SH EXPERT OPTIONS
+
+.TP
+.B --amino
+Force the sequence alignment to be interpreted as amino acid
+sequences. Normally HMMER autodetects whether the alignment is
+protein or DNA, but sometimes alignments are so small that
+autodetection is ambiguous. See
+.B --nucleic.
+
+.TP
+.BI --archpri " <x>"
+Set the "architecture prior" used by MAP architecture construction to 
+.I <x>,
+where 
+.I <x>
+is a probability between 0 and 1. This parameter governs a geometric
+prior distribution over model lengths. As
+.I <x> 
+increases, longer models are favored a priori.
+As 
+.I <x>
+decreases, it takes more residue conservation in a column to
+make a column a "consensus" match column in the model architecture.
+The 0.85 default has been chosen empirically as a reasonable setting.
+
+.TP
+.B --binary
+Write the HMM to
+.I hmmfile
+in HMMER binary format instead of readable ASCII text.
+
+.TP
+.BI --cfile " <f>"
+Save the observed emission and transition counts to 
+.I <f> 
+after the architecture has been determined (e.g. after residues/gaps
+have been assigned to match, delete, and insert states).
+This option is used in HMMER development for generating data files
+useful for training new Dirichlet priors. The format of
+count files is documented in the User's Guide.
+
+.TP
+.B --fast
+Quickly and heuristically determine the architecture of the model by
+assigning all columns will more than a certain fraction of gap
+characters to insert states. By default this fraction is 0.5, and it
+can be changed using the
+.B --gapmax
+option.
+The default construction algorithm is a maximum a posteriori (MAP)
+algorithm, which is slower. 
+
+.TP
+.BI --gapmax " <x>"
+Controls the 
+.I --fast
+model construction algorithm, but if 
+.I --fast
+is not being used, has no effect.
+If a column has more than a fraction
+.I <x>
+of gap symbols in it, it gets assigned to an insert column.
+.I <x> 
+is a frequency from 0 to 1, and by default is set
+to 0.5. Higher values of
+.I <x>
+mean more columns get assigned to consensus, and models get
+longer; smaller values of 
+.I <x> 
+mean fewer columns get assigned to consensus, and models get
+smaller.
+.I <x>
+
+.TP
+.B --hand
+Specify the architecture of the model by hand: the alignment file must
+be in SELEX or Stockholm format, and the reference annotation
+line (#=RF in SELEX, #=GC RF in Stockholm) is used to specify
+the architecture. Any column marked with a non-gap symbol (such
+as an 'x', for instance) is assigned as a consensus (match) column in
+the model.
+
+.TP 
+.BI --idlevel " <x>"
+Controls both the determination of effective sequence number and
+the behavior of the 
+.I --wblosum 
+weighting option. The sequence alignment is clustered by percent
+identity, and the number of clusters at a cutoff threshold of 
+.I <x> 
+is used to determine the effective sequence number.
+Higher values of 
+.I <x> 
+give more clusters and higher effective sequence
+numbers; lower values of 
+.I <x> 
+give fewer clusters and lower effective sequence numbers.
+.I <x> 
+is a fraction from 0 to 1, and 
+by default is set to 0.62 (corresponding to the clustering level used
+in constructing the BLOSUM62 substitution matrix).
+
+.TP
+.BI --informat " <s>"
+Assert that the input 
+.I seqfile
+is in format
+.I <s>;
+do not run Babelfish format autodection. This increases
+the reliability of the program somewhat, because 
+the Babelfish can make mistakes; particularly
+recommended for unattended, high-throughput runs
+of HMMER. Valid format strings include FASTA,
+GENBANK, EMBL, GCG, PIR, STOCKHOLM, SELEX, MSF,
+CLUSTAL, and PHYLIP. See the User's Guide for a complete
+list.
+
+.TP
+.B --noeff
+Turn off the effective sequence number calculation, and use the
+true number of sequences instead. This will usually reduce the
+sensitivity of the final model (so don't do it without good reason!)
+
+.TP
+.B --nucleic
+Force the alignment to be interpreted as nucleic acid sequence,
+either RNA or DNA. Normally HMMER autodetects whether the alignment is
+protein or DNA, but sometimes alignments are so small that
+autodetection is ambiguous. See
+.B --amino.
+
+.TP
+.BI --null " <f>"
+Read a null model from 
+.I <f>.
+The default for protein is to use average amino acid frequencies from
+Swissprot 34 and p1 = 350/351; for nucleic acid, the default is
+to use 0.25 for each base and p1 = 1000/1001. For documentation
+of the format of the null model file and further explanation
+of how the null model is used, see the User's Guide.
+
+.TP
+.BI --pam " <f>"
+Apply a heuristic PAM- (substitution matrix-) based prior on match
+emission probabilities instead of
+the default mixture Dirichlet. The substitution matrix is read
+from 
+.I <f>. 
+See 
+.B --pamwgt. 
+
+The default Dirichlet state transition prior and insert emission prior
+are unaffected. Therefore in principle you could combine 
+.B --prior
+with
+.B --pam
+but this isn't recommended, as it hasn't been tested. (
+.B --pam
+itself hasn't been tested much!)
+
+.TP 
+.BI --pamwgt " <x>"
+Controls the weight on a PAM-based prior. Only has effect if
+.B --pam 
+option is also in use. 
+.I <x>
+is a positive real number, 20.0 by default. 
+.I <x>
+is the number of "pseudocounts" contriubuted by the heuristic
+prior. Very high values of 
+.I <x> 
+can force a scoring system that is entirely driven by the
+substitution matrix, making
+HMMER somewhat approximate Gribskov profiles.
+
+.TP
+.BI --pbswitch " <n>"
+For alignments with a very large number of sequences, 
+the GSC, BLOSUM, and Voronoi weighting schemes are slow;
+they're O(N^2) for N sequences. Henikoff position-based
+weights (PB weights) are more efficient. At or above a certain
+threshold sequence number
+.I <n> 
+.B hmmbuild 
+will switch from GSC, BLOSUM, or Voronoi weights to
+PB weights. To disable this switching behavior (at the cost
+of compute time, set 
+.I <n>
+to be something larger than the number of sequences in
+your alignment.
+.I <n>
+is a positive integer; the default is 1000.
+
+.TP
+.BI --prior " <f>"
+Read a Dirichlet prior from 
+.I <f>, 
+replacing the default mixture Dirichlet.
+The format of prior files is documented in the User's Guide,
+and an example is given in the Demos directory of the HMMER
+distribution.
+
+.TP
+.BI --swentry " <x>"
+Controls the total probability that is distributed to local entries
+into the model, versus starting at the beginning of the model
+as in a global alignment.
+.I <x>
+is a probability from 0 to 1, and by default is set to 0.5.
+Higher values of
+.I <x>
+mean that hits that are fragments on their left (N or 5'-terminal) side will be
+penalized less, but complete global alignments will be penalized more.
+Lower values of
+.I <x>
+mean that fragments on the left will be penalized more, and
+global alignments on this side will be favored.
+This option only affects the configurations that allow local
+alignments,
+e.g. 
+.B -s
+and
+.B -f;
+unless one of these options is also activated, this option has no effect.
+You have independent control over local/global alignment behavior for
+the N/C (5'/3') termini of your target sequences using 
+.B --swentry
+and
+.B --swexit.
+
+.TP 
+.BI --swexit " <x>"
+Controls the total probability that is distributed to local exits
+from the model, versus ending an alignment at the end of the model
+as in a global alignment.
+.I <x>
+is a probability from 0 to 1, and by default is set to 0.5.
+Higher values of
+.I <x>
+mean that hits that are fragments on their right (C or 3'-terminal) side will be
+penalized less, but complete global alignments will be penalized more.
+Lower values of
+.I <x>
+mean that fragments on the right will be penalized more, and
+global alignments on this side will be favored.
+This option only affects the configurations that allow local
+alignments,
+e.g. 
+.B -s
+and
+.B -f;
+unless one of these options is also activated, this option has no effect.
+You have independent control over local/global alignment behavior for
+the N/C (5'/3') termini of your target sequences using 
+.B --swentry
+and
+.B --swexit.
+
+.TP 
+.B --verbose 
+Print more possibly useful stuff, such as the individual scores for
+each sequence in the alignment.
+
+.TP 
+.B --wblosum
+Use the BLOSUM filtering algorithm to weight the sequences,
+instead of the default.
+Cluster the sequences at a given percentage identity
+(see
+.B --idlevel);
+assign each cluster a total weight of 1.0, distributed equally
+amongst the members of that cluster.
+
+
+.TP
+.B --wgsc
+Use the Gerstein/Sonnhammer/Chothia ad hoc sequence weighting
+algorithm. This is already the default, so this option has no effect
+(unless it follows another option in the --w family, in which case it
+overrides it).
+
+.TP
+.B --wme
+Use the Krogh/Mitchison maximum entropy algorithm to "weight"
+the sequences. This supercedes the Eddy/Mitchison/Durbin
+maximum discrimination algorithm, which gives almost
+identical weights but is less robust. ME weighting seems 
+to give a marginal increase in sensitivity
+over the default GSC weights, but takes a fair amount of time.
+
+.TP 
+.B --wnone
+Turn off all sequence weighting.
+
+.TP
+.B --wpb
+Use the Henikoff position-based weighting scheme. 
+
+.TP
+.B --wvoronoi
+Use the Sibbald/Argos Voronoi sequence weighting algorithm
+in place of the default GSC weighting.

+
+.TP
+.BI --fixed " <n>"
+Fix the length of the random sequences to

+is a positive (and reasonably sized) integer.
+The default is instead to generate sequences with
+a variety of different lengths, controlled by a Gaussian

+is a positive real number. The default is 350.
+
+.TP
+.BI --num " <n>"
+Set the number of synthetic sequences to 
+.I <n>,
+where 
+.I <n>
+is a positive integer. If
+.I <n> is less than about 1000, the fit to the EVD may fail.
+Higher numbers of

+.SH SYNOPSIS
+.B hmmemit
+.I [options]
+.I hmmfile
+
+.SH DESCRIPTION
+
+.B hmmemit
+reads an HMM file from
+.I hmmfile
+containing one or more HMMs,
+and generates a number of sequences from each HMM;
+or, if the
+.B -c
+option is selected, generate a single majority-rule consensus.
+This can be useful for various applications in which one needs a simulation
+of sequences consistent with a sequence family consensus. 
+
+.pp
+By default,
+.B hmmemit
+generates 10 sequences and outputs them in FASTA (unaligned) format.
+
+.SH OPTIONS
+
+.TP
+.B -a
+Write the generated sequences in an aligned format (SELEX) rather than
+FASTA.
+
+.TP
+.B -c
+Predict a single majority-rule consensus sequence instead of sampling
+sequences from the HMM's probability distribution.  Highly conserved
+residues (p >= 0.9 for DNA, p >= 0.5 for protein) are shown in upper
+case; others are shown in lower case.  Some insert states may become
+part of the majority rule consensus, because they are used in >= 50%
+of generated sequences; when this happens, insert-generated residues
+are simply shown as "x".
+
+.TP
+.B -h
+Print brief help; includes version number and summary of
+all options, including expert options.
+
+.TP
+.BI -n " <n>"
+Generate
+.I <n> 
+sequences. Default is 10.
+
+.TP
+.BI -o " <f>"
+Save the synthetic sequences to file
+.I <f>
+rather than writing them to stdout.
+
+.TP
+.B -q
+Quiet; suppress all output except for the sequences themselves.
+Useful for piping or directing the output.
+
+.SH EXPERT OPTIONS
+
+.TP
+.BI --seed " <n>"
+Set the random seed to
+.I <n>,
+where 
+.I <n> 
+is a positive integer. The default is to use 
+.B time()
+to generate a different seed for each run, which
+means that two different runs of
+.B hmmemit
+on the same HMM will give slightly different
+results.  You can use
+this option to generate reproducible results.

+.TP
+.B hmmalign
+Align multiple sequences to a profile HMM.
+
+.TP
+.B hmmbuild
+Build a profile HMM from a given multiple sequence alignment.
+
+.TP
+.B hmmcalibrate
+Determine appropriate statistical significance parameters 
+for a profile HMM prior to doing database searches.
+
+.TP 
+.B hmmconvert
+Convert HMMER profile HMMs to other formats, such as GCG profiles.
+
+.TP
+.B hmmemit
+Generate sequences probabilistically from a profile HMM.
+
+.TP
+.B hmmfetch
+Retrieve an HMM from an HMM database
+
+.TP 
+.B hmmindex
+Create a binary SSI index for an HMM database
+
+.TP
+.B hmmpfam
+Search a profile HMM database with a sequence (i.e., annotate various
+kinds of domains in the query sequence).
+
+.TP
+.B hmmsearch
+Search a sequence database with a profile HMM (i.e., find additional
+homologues of a modeled family). 
+
+.SH DESCRIPTION
+
+These programs use profile hidden Markov models (profile HMMs) to
+model the primary structure consensus of a family of protein or
+nucleic acid sequences. 
+
+.SH OPTIONS
+
+.PP
+All
+.B HMMER 
+programs give a brief summary of their command-line syntax and options
+if invoked without any arguments.
+When invoked with the single argument,
+.B -h
+(i.e., help), a program will report more verbose command-line usage
+information, including rarely used, experimental, and expert options.
+.B -h
+will report version numbers which are useful if
+you need to report a bug or problem to me.
+
+.PP
+Each
+.B HMMER
+program has its own man page briefly summarizing command line usage.
+There is also a user's guide that came
+with the software distribution, which includes a tutorial introduction
+and more detailed descriptions of the programs.
+
+See http://hmmer.wustl.edu/ for on-line documentation and
+the current HMMER release.
+
+.PP
+In general, no command line options should be needed by beginning users.
+The defaults are set up for optimum performance in most situations.
+Options that are single lowercase letters (e.g. 
+.B -a
+) are "common" options that are expected to be frequently used
+and will be important in many applications.
+Options that are single uppercase letters (e.g. 
+.B -B
+) are usually less common options, but also may be important
+in some applications.
+Options that are full words (e.g. 
+.B --verbose
+) are either rarely used, experimental, or expert options. 
+Some experimental options are only there for my own ongoing experiments
+with HMMER, and may not be supported or documented adequately. 
+
+
+.SH SEQUENCE FILE FORMATS
+
+In general,
+.B HMMER
+attempts to read most common biological sequence file formats.
+It autodetects the format of the file. It also autodetects
+whether the sequences are protein or nucleic acid. 
+Standard IUPAC degeneracy codes are allowed in addition
+to the usual 4-letter or 20-letter codes. 
+
+.TP
+.B Unaligned sequences
+Unaligned sequence files may be in FASTA, Swissprot, EMBL, GenBank,
+PIR, Intelligenetics, Strider, or GCG format. 
+These formats
+are documented in the User's Guide.
+
+.TP 
+.B Sequence alignments
+Multiple sequence alignments may be in CLUSTALW, SELEX, or GCG MSF
+format. These formats
+are documented in the User's Guide.
+
+.SH ENVIRONMENT VARIABLES
+
+For ease of using large stable sequence and HMM databases,
+.B HMMER
+looks for sequence files and HMM files in the current
+working directory as well as in system directories specified
+by environment variables.
+
+.TP
+.B BLASTDB
+Specifies the directory location of sequence databases. Example:
+.B /seqlibs/blast-db/.
+In installations that use BLAST software, this environment variable
+is likely to already be set.
+
+.TP
+.B HMMERDB
+Specifies the directory location of HMM databases. Example:
+.B /seqlibs/pfam/.

+
+.SH SYNOPSIS
+.B hmmpfam
+.I [options]
+.I hmmfile
+.I seqfile
+
+.SH DESCRIPTION
+
+.B hmmpfam
+reads a sequence file
+.I seqfile
+and compares each sequence in it, one at a time, against all the HMMs in
+.I hmmfile
+looking for significantly similar sequence matches.
+
+.PP
+.I hmmfile
+will be looked for first in the current working directory,
+then in a directory named by the environment variable
+.I HMMERDB.
+This lets administrators install HMM library(s) such as
+Pfam in a common location.
+
+.PP
+There is a separate output report for each sequence in
+.I seqfile.
+This report consists of three sections: a ranked list
+of the best scoring HMMs, a list of the
+best scoring domains in order of their occurrence
+in the sequence, and alignments for all the best scoring
+domains.
+A sequence score may be higher than a domain score for
+the same sequence if there is more than one domain in the sequence;
+the sequence score takes into account all the domains.
+All sequences scoring above the 
+.I -E
+and
+.I -T 
+cutoffs are shown in the first list, then 
+.I every 
+domain found in this list is
+shown in the second list of domain hits.
+If desired, E-value and bit score thresholds may also be applied
+to the domain list using the
+.I --domE
+and
+.I --domT
+options.
+
+.SH OPTIONS
+
+.TP
+.B -h
+Print brief help; includes version number and summary of
+all options, including expert options.
+
+.TP
+.B -n
+Specify that models and sequence are nucleic acid, not protein.
+Other HMMER programs autodetect this; but because of the order in
+which 
+.B hmmpfam
+accesses data, it can't reliably determine the correct "alphabet"
+by itself.
+
+.TP
+.BI -A " <n>"
+Limits the alignment output to the 
+.I <n>
+best scoring domains.
+.B -A0
+shuts off the alignment output and can be used to reduce
+the size of output files.
+
+.TP
+.BI -E " <x>"
+Set the E-value cutoff for the per-sequence ranked hit list to 
+.I <x>,
+where
+.I <x>
+is a positive real number. The default is 10.0. Hits with E-values
+better than (less than) this threshold will be shown.
+
+.TP 
+.BI -T " <x>"
+Set the bit score cutoff for the per-sequence ranked hit list to
+.I <x>,
+where
+.I <x> 
+is a real number.
+The default is negative infinity; by default, the threshold
+is controlled by E-value and not by bit score.
+Hits with bit scores better than (greater than) this threshold
+will be shown.
+
+.TP
+.BI -Z " <n>"
+Calculate the E-value scores as if we had seen a sequence database of 
+.I <n>
+sequences. The default is arbitrarily set to 59021, the size of
+Swissprot 34.
+
+.SH EXPERT OPTIONS
+
+.TP
+.B --acc
+Report HMM accessions instead of names in the output reports.
+Useful for high-throughput annotation, where the data are being
+parsed for storage in a relational database.
+
+.TP
+.B --compat
+Use the output format of HMMER 2.1.1, the 1998-2001 public
+release; provided so 2.1.1 parsers don't have to be rewritten.
+
+.TP
+.BI --cpu " <n>"
+Sets the maximum number of CPUs that the program
+will run on. The default is to use all CPUs
+in the machine. Overrides the HMMER_NCPU
+environment variable. Only affects threaded
+versions of HMMER (the default on most systems).
+
+.TP
+.B --cut_ga
+Use Pfam GA (gathering threshold) score cutoffs. 
+Equivalent
+to --globT <GA1> --domT <GA2>, but the GA1 and GA2 cutoffs
+are read from each HMM in
+.I hmmfile
+individually. hmmbuild puts these cutoffs there
+if the alignment file was annotated in a Pfam-friendly
+alignment format (extended SELEX or Stockholm format) and 
+the optional GA annotation line was present. If these
+cutoffs are not set in the HMM file, 
+.B --cut_ga 
+doesn't work.
+
+.TP
+.B --cut_tc
+Use Pfam TC (trusted cutoff) score cutoffs. Equivalent
+to --globT <TC1> --domT <TC2>, but the TC1 and TC2 cutoffs
+are read from each HMM in
+.I hmmfile
+individually. hmmbuild puts these cutoffs there
+if the alignment file was annotated in a Pfam-friendly
+alignment format (extended SELEX or Stockholm format) and 
+the optional TC annotation line was present. If these
+cutoffs are not set in the HMM file, 
+.B --cut_tc
+doesn't work.
+
+.TP
+.B --cut_nc
+Use Pfam NC (noise cutoff) score cutoffs. Equivalent
+to --globT <NC1> --domT <NC2>, but the NC1 and NC2 cutoffs
+are read from each HMM in
+.I hmmfile
+individually. hmmbuild puts these cutoffs there
+if the alignment file was annotated in a Pfam-friendly
+alignment format (extended SELEX or Stockholm format) and 
+the optional NC annotation line was present. If these
+cutoffs are not set in the HMM file, 
+.B --cut_nc
+doesn't work.
+
+.TP
+.BI --domE " <x>"
+Set the E-value cutoff for the per-domain ranked hit list to
+.I <x>,
+where 
+.I <x>
+is a positive real number.
+The default is infinity; by default, all domains in the sequences
+that passed the first threshold will be reported in the second list,
+so that the number of domains reported in the per-sequence list is
+consistent with the number that appear in the per-domain list.
+
+.TP 
+.BI --domT " <x>"
+Set the bit score cutoff for the per-domain ranked hit list to
+.I <x>,
+where 
+.I <x>
+is a real number. The default is negative infinity; 
+by default, all domains in the sequences
+that passed the first threshold will be reported in the second list,
+so that the number of domains reported in the per-sequence list is
+consistent with the number that appear in the per-domain list.
+.I Important note:
+only one domain in a sequence is absolutely controlled by this
+parameter, or by
+.B --domT. 
+The second and subsequent domains in a sequence have a de facto
+bit score threshold of 0 because of the details of how HMMER
+works. HMMER requires at least one pass through the main model
+per sequence; to do more than one pass (more than one domain)
+the multidomain alignment must have a better score than the
+single domain alignment, and hence the extra domains must contribute
+positive score. See the Users' Guide for more detail.
+
+.TP
+.BI --forward
+Use the Forward algorithm instead of the Viterbi algorithm
+to determine the per-sequence scores. Per-domain scores are
+still determined by the Viterbi algorithm. Some have argued that
+Forward is a more sensitive algorithm for detecting remote
+sequence homologues; my experiments with HMMER have not
+confirmed this, however.
+
+.TP
+.BI --informat " <s>"
+Assert that the input 
+.I seqfile
+is in format
+.I <s>;
+do not run Babelfish format autodection. This increases
+the reliability of the program somewhat, because 
+the Babelfish can make mistakes; particularly
+recommended for unattended, high-throughput runs
+of HMMER. Valid format strings include FASTA,
+GENBANK, EMBL, GCG, PIR, STOCKHOLM, SELEX, MSF,
+CLUSTAL, and PHYLIP. See the User's Guide for a complete
+list.
+
+.TP 
+.B --null2
+Turn off the post hoc second null model. By default, each alignment
+is rescored by a postprocessing step that takes into account possible
+biased composition in either the HMM or the target sequence.
+This is almost essential in database searches, especially with
+local alignment models. There is a very small chance that this
+postprocessing might remove real matches, and 
+in these cases
+.B --null2 
+may improve sensitivity at the expense of reducing
+specificity by letting biased composition hits through.
+
+.TP
+.B --pvm
+Run on a Parallel Virtual Machine (PVM). The PVM must
+already be running. The client program 
+.B hmmpfam-pvm
+must be installed on all the PVM nodes.
+The HMM database
+.I hmmfile
+and an associated GSI index file
+.IR hmmfile. gsi
+must also be installed on all the PVM nodes.
+(The GSI index is produced by the program
+.BR hmmindex .)
+Because the PVM implementation is I/O bound,
+it is highly recommended that each node have a
+local copy of 
+.I hmmfile
+rather than NFS mounting a shared copy.
+Optional PVM support must have been compiled into 
+HMMER for
+.B --pvm
+to function.
+
+.TP
+.B --xnu
+Turn on XNU filtering of target protein sequences. Has no effect
+on nucleic acid sequences. In trial experiments, 
+.B --xnu
+appears to perform less well than the default
+post hoc null2 model.

+shuts off the alignment output and can be used to reduce
+the size of output files.
+
+.TP
+.BI -E " <x>"
+Set the E-value cutoff for the per-sequence ranked hit list to 
+.I <x>,
+where
+.I <x>
+is a positive real number. The default is 10.0. Hits with E-values
+better than (less than) this threshold will be shown.
+
+.TP 
+.BI -T " <x>"
+Set the bit score cutoff for the per-sequence ranked hit list to
+.I <x>,
+where
+.I <x> 
+is a real number.
+The default is negative infinity; by default, the threshold
+is controlled by E-value and not by bit score.
+Hits with bit scores better than (greater than) this threshold
+will be shown.
+
+.TP
+.BI -Z " <n>"
+Calculate the E-value scores as if we had seen a sequence database of 
+.I <n>
+sequences. The default is the number of sequences seen in your
+database file 
+.I <seqfile>.
+
+.SH EXPERT OPTIONS
+
+.TP
+.B --compat
+Use the output format of HMMER 2.1.1, the 1998-2001 public
+release; provided so 2.1.1 parsers don't have to be rewritten.
+
+.TP
+.BI --cpu " <n>"
+Sets the maximum number of CPUs that the program
+will run on. The default is to use all CPUs
+in the machine. Overrides the HMMER_NCPU
+environment variable. Only affects threaded
+versions of HMMER (the default on most systems).
+
+.TP
+.B --cut_ga
+Use Pfam GA (gathering threshold) score cutoffs. 
+Equivalent
+to --globT <GA1> --domT <GA2>, but the GA1 and GA2 cutoffs
+are read from the HMM file. hmmbuild puts these cutoffs there
+if the alignment file was annotated in a Pfam-friendly
+alignment format (extended SELEX or Stockholm format) and 
+the optional GA annotation line was present. If these
+cutoffs are not set in the HMM file, 
+.B --cut_ga 
+doesn't work.
+
+.TP
+.B --cut_tc
+Use Pfam TC (trusted cutoff) score cutoffs. Equivalent
+to --globT <TC1> --domT <TC2>, but the TC1 and TC2 cutoffs
+are read from the HMM file. hmmbuild puts these cutoffs there
+if the alignment file was annotated in a Pfam-friendly
+alignment format (extended SELEX or Stockholm format) and 
+the optional TC annotation line was present. If these
+cutoffs are not set in the HMM file, 
+.B --cut_tc
+doesn't work.
+
+.TP
+.B --cut_nc
+Use Pfam NC (noise cutoff) score cutoffs. Equivalent
+to --globT <NC1> --domT <NC2>, but the NC1 and NC2 cutoffs
+are read from the HMM file. hmmbuild puts these cutoffs there
+if the alignment file was annotated in a Pfam-friendly
+alignment format (extended SELEX or Stockholm format) and 
+the optional NC annotation line was present. If these
+cutoffs are not set in the HMM file, 
+.B --cut_nc
+doesn't work.
+
+.TP
+.BI --domE " <x>"
+Set the E-value cutoff for the per-domain ranked hit list to
+.I <x>,
+where 
+.I <x>
+is a positive real number.
+The default is infinity; by default, all domains in the sequences
+that passed the first threshold will be reported in the second list,
+so that the number of domains reported in the per-sequence list is
+consistent with the number that appear in the per-domain list.
+
+.TP 
+.BI --domT " <x>"
+Set the bit score cutoff for the per-domain ranked hit list to
+.I <x>,
+where 
+.I <x>
+is a real number. The default is negative infinity; 
+by default, all domains in the sequences
+that passed the first threshold will be reported in the second list,
+so that the number of domains reported in the per-sequence list is
+consistent with the number that appear in the per-domain list.
+.I Important note:
+only one domain in a sequence is absolutely controlled by this
+parameter, or by
+.B --domT. 
+The second and subsequent domains in a sequence have a de facto
+bit score threshold of 0 because of the details of how HMMER
+works. HMMER requires at least one pass through the main model
+per sequence; to do more than one pass (more than one domain)
+the multidomain alignment must have a better score than the
+single domain alignment, and hence the extra domains must contribute
+positive score. See the Users' Guide for more detail.
+
+.TP
+.BI --forward
+Use the Forward algorithm instead of the Viterbi algorithm
+to determine the per-sequence scores. Per-domain scores are
+still determined by the Viterbi algorithm. Some have argued that
+Forward is a more sensitive algorithm for detecting remote
+sequence homologues; my experiments with HMMER have not
+confirmed this, however.
+
+.TP
+.BI --informat " <s>"
+Assert that the input 
+.I seqfile
+is in format
+.I <s>;
+do not run Babelfish format autodection. This increases
+the reliability of the program somewhat, because 
+the Babelfish can make mistakes; particularly
+recommended for unattended, high-throughput runs
+of HMMER. Valid format strings include FASTA,
+GENBANK, EMBL, GCG, PIR, STOCKHOLM, SELEX, MSF,
+CLUSTAL, and PHYLIP. See the User's Guide for a complete
+list.
+
+.TP 
+.B --null2
+Turn off the post hoc second null model. By default, each alignment
+is rescored by a postprocessing step that takes into account possible
+biased composition in either the HMM or the target sequence.
+This is almost essential in database searches, especially with
+local alignment models. There is a very small chance that this
+postprocessing might remove real matches, and 
+in these cases
+.B --null2 
+may improve sensitivity at the expense of reducing
+specificity by letting biased composition hits through.
+
+.TP
+.B --pvm
+Run on a Parallel Virtual Machine (PVM). The PVM must
+already be running. The client program 
+.B hmmsearch-pvm
+must be installed on all the PVM nodes.
+Optional PVM support must have been compiled into 
+HMMER.
+
+.TP
+.B --xnu
+Turn on XNU filtering of target protein sequences. Has no effect
+on nucleic acid sequences. In trial experiments, 
+.B --xnu
+appears to perform less well than the default
+post hoc null2 model.

+\chapter {Sequence file formats}
+
+\section{Summary}
+
+The software can handle a number of different file formats. By
+default, it autodetects the file format, so you don't have to worry
+about converting formats. Most common file formats are recognized,
+including FASTA, Genbank, EMBL, Swissprot, PIR, and FASTA for
+unaligned sequences, and GCG MSF, Clustal, Phylip, and Stockholm
+format for multiple sequence alignments. Some parts of the source code
+call the autodetector the ``Babelfish''. 
+
+The Babelfish has three drawbacks. First, it takes a small amount of
+time to do the autodetection. Second, the Babelfish is aggressive, and
+it makes mistakes when a file isn't one of the known formats -- in
+particular, it can recognize plain text files as SELEX alignments,
+because the SELEX format is so free-form. Third, because the Babelfish
+works by reading the first part of the file then rewinding it before
+starting to process it, you can't use the Babelfish on a nonrewindable
+stream: e.g. when you're taking sequence input from a UNIX pipe
+instead of a file, or when the file is gzipped and has to be
+decompressed before processing.  In normal use, when you're using the
+software interactively from the command line on sequence files that
+you're familiar with, the Babelfish is very convenient and
+(relatively) safe.
+
+However, you'll find that there are times when you want to override
+the Babelfish -- particularly in high-throughput analysis, when you
+know the format your files are supposed to be in, and you'd rather
+increase robustness and sacrifice interactive flexibility. All the
+programs have an \verb+--informat <format>+ option that lets you
+specify the format and shut off the Babelfish. You \emph{must} use
+\verb+--informat+ to use compressed files, or to read sequence from a
+UNIX pipe... see below for more details on these tricks.
+
+\section{Formats recognized by the Babelfish}
+
+Recognized unaligned sequence file formats:
+
+\begin{tabular}{ll}\hline
+Format name   & Note \\ \hline
+fasta         & BLAST flatfile databases, etc.\\
+genbank       & NCBI Genbank flat file format.\\
+embl          & Includes both EMBL (DNA) and SWISSPROT (protein) databases.\\
+pir           & Protein Information Resource database (NBRF/Georgetown)\\
+gcg           & Wisconsin Genetics Computer Group; only allows one sequence per file.\\
+gcgdata       & I think this GCG database format is obsolete now.\\ \hline
+\end{tabular}
+
+Recognized multiple sequence alignment file formats:
+
+\begin{tabular}{ll}\hline
+Format name   & Note \\ \hline
+stockholm     & Pfam format. Allows databases of more than one alignment per file\\
+selex         & Old NeXagen RNA alignment format, adopted by early HMMER releases.\\
+msf           & GCG's alignment format.\\
+clustal       & ClustalV, ClustalW, and friends.\\
+a2m           & Aligned FASTA format; see comment below.\\
+phylip        & Format used by Felsenstein's PHYLIP phylogenetic inference software\\\hline
+\end{tabular}
+
+Aligned FASTA format (here called ``A2M'', though I believe that what
+Haussler's group at UCSC started calling A2M is yet another variant of
+aligned FASTA that's incompatible with this A2M) is only autodetected
+when an alignment file is expected. Otherwise an A2M file will be
+recognized as unaligned FASTA, and its gap characters (if any) will be
+parsed as sequence characters -- often not what you want.
+
+Alignment files may be used when unaligned files are expected -- the
+sequences will silently be de-aligned and read sequentially. The
+converse is not true; you can't give an unaligned sequence format when
+an alignment is expected (makes sense, right?).
+
+There is no provision for enforcing that single unaligned sequence
+formats really do contain just a single sequence.  An attempt to
+convert a multisequence file to GCG format will silently ``succeed'',
+and the file may look ok to your eye, but that multisequence ``GCG''
+file is illegal. The data will be corrupted if you try to read that
+file back in, possibly without generating any error messages.
+
+It turns out that other formats work too, but they're undocumented,
+not subjected to any quality control testing at software release time,
+and prone to change without notice at my slightest whim. (In other
+words, even less supported than the software already is.) The brave,
+curious, or desperate are invited to peruse
+\prog{seqio.c} and \prog{squid.h}.
+
+\section{Special tricks}
+
+\subsection{Reading from standard input (probably UNIX-only)}
+
+If you give ``-'' as a sequence filename, the software will read the
+sequences from standard input rather than from a file. You will need
+to specify the format of the incoming data using the
+\verb+--informat+ option.
+Any format except SELEX can be read from standard input. This lets you
+use any program downstream in a standard UNIX pipe.
+
+There is one limitation: you can't use ``-'' more than once on a
+command line, for obvious reasons. (How is it supposed to read more
+than one file from one standard input stream?) If you do, behavior of
+the software is undefined -- in other words, the software don't check
+for whether you're making this mistake, so God help you if you do.
+
+\subsection{Reading from gzip'ed files (probably UNIX-only)}
+
+A sequence file in any format except SELEX can be compressed by gzip,
+and read in its compressed form. The software looks for the suffix
+\prog{.gz} to detect gzip'ed files. This allows you to save disk space
+by keeping sequence files gzip'ed, if you like. gzip is not built in;
+the software needs to find a gzip executable in your current PATH.
+
+If for some reason you name a file with a \prog{.gz} suffix and it's
+\emph{not} a gzip-compressed file, the software will still try to
+decompress it, and peculiar things may happen.
+
+\section{FASTA format, the recommended unaligned format}
+
+FASTA is probably the simplest of formats for unaligned sequences.
+FASTA files are easily created in a text editor.  Each sequence is
+preceded by a line starting with \verb+>+. The first word on this line
+is the name of the sequence. The rest of the line is a description of
+the sequence (free format). The remaining lines contain the sequence
+itself. You can put as many letters on a sequence line as you want.
+
+\textbf{Example of a simple FASTA file:}
+\begin{verbatim}
+>seq1 This is the description of my first sequence.
+AGTACGTAGTAGCTGCTGCTACGTGCGCTAGCTAGTACGTCA CGACGTAGATGCTAGCTGACTCGATGC
+>seq2 This is a description of my second sequence.
+CGATCGATCGTACGTCGACTGATCGTAGCTACGTCGTACGTAG CATCGTCAGTTACTGCATGCTCG
+\end{verbatim}
+
+For better or worse, FASTA is not a documented standard. Minor (and
+major) variants are in widespread use in the bioinformatics community,
+all of which are called ``FASTA format''. My software attempts to
+cater to all of them, and is tolerant of common deviations in FASTA
+format. Certainly anything that is accepted by the database formatting
+programs in NCBI BLAST or WU-BLAST (e.g. setdb, pressdb, xdformat)
+will also be accepted by my software. Blank lines in a FASTA file are
+ignored, and so are spaces or other gap symbols (dashes, underscores,
+periods) in a sequence. Other non-amino or non-nucleic acid symbols in
+the sequence are also silently ignored, mostly because some people
+seem to think that ``*'' or ``.'' should be added to protein sequences
+to (redundantly) indicate the end of the sequence. The parser will
+also accept unlimited line lengths, which allows it to accomodate the
+enormous description lines in the NCBI NR databases.
+
+On the other hand, any FASTA files \emph{generated} by my software
+adhere closely to community standards, and should be usable by other
+software packages (BLAST, FASTA, etc.) that are more picky about
+parsing their input files. That means you can run a sloppy FASTA file
+thru \prog{sreformat} to clean it up.
+
+Partly because of this tolerance, the software may have a difficult
+time dealing with files that are \textit{not} in FASTA format,
+especially if you're relying on the Babelfish to do format
+autodetection.  Some (now mercifully uncommon) file formats are so
+similar to FASTA format that they be erroneously called FASTA by the
+Babelfish and then quietly but lethally misparsed. An example is the
+old NBRF file format. If you're using \verb+--informat+, things will
+be more robust, and the software should simply refuse to accept a
+non-FASTA file -- but you shouldn't count on this, because files
+perversely similar to FASTA will still confuse the parser.  (The gist
+of these caveats applies to all formats, not just FASTA.)
+
+\section{SELEX, the quick and dirty alignment format}
+
+An example of a simple SELEX alignment file:
+
+\begin{verbatim}
+# Example selex file
+
+seq1     ACGACGACGACG.
+seq2     ..GGGAAAGG.GA
+seq3     UUU..AAAUUU.A
+
+seq1  ..ACG
+seq2  AAGGG
+seq3  AA...UUU
+\end{verbatim}
+
+SELEX is an interleaved multiple alignment format that arose as a
+simple, intuitive format that was easy to write and manipulate
+manually in a text editor. It is usually easy to convert other
+alignment formats into SELEX format, even with a couple of lines of
+Perl, but it can be harder to go the other way, since SELEX is more
+free-format than other alignment formats. For instance, GCG's MSF
+format and the output of the CLUSTALV multiple alignment program are
+similar interleaved formats that can be converted to SELEX just by
+stripping a small number of non-sequence lines out. Because SELEX
+evolved to accomodate different user input styles, it is very tolerant
+of various inconsistencies such as different gap symbols, varying line
+lengths, etc.
+
+Each line contains a name, followed by the aligned sequence. A space,
+dash, underscore, or period denotes a gap. If the alignment is too
+long to fit on one line, the alignment is split into multiple blocks,
+separated by blank lines. The number of sequences, their order, and
+their names must be the same in every block (even if a sequence has no
+residues in a given block!) Other blank lines are ignored. You can add
+comments to the file on lines starting with a \verb+#+.
+
+SELEX stands for ``Systematic Evolution of Ligands by Exponential
+Enrichment'' -- it refers to the Tuerk and Gold technology for
+evolving families of small RNAs for particular functions
+\cite{Tuerk90b}. SELEX files were what we used to keep track of
+alignments of these small RNA families, at a company then called
+NeXagen, in Boulder. It's an interesting piece of historical baggage.
+With the development of HMMER and more need for annotated alignments
+in Pfam, SELEX format later evolved into ``extended SELEX'', with a
+reserved comment style that allowed structural markup and other
+annotations, but that became unwieldy. We now use Stockholm format
+(see below) for highly annotated alignments. (Extended SELEX is
+deprecated and undocumented.) Still, the basic SELEX format remains a
+useful ``lowest common denominator'' alignment format, and has been
+retained.
+
+\subsubsection {Detailed specification of a SELEX file}
+
+\begin{enumerate}
+\item
+Any line beginning with a \verb+#=+ as the first two characters is a
+parsed machine comment in extended SELEX, and is now deprecated. 
+
+\item
+All other lines beginning with a \verb+%+ or \verb+#+ as the first
+character are user comments.  User comments are ignored by all
+software. Anything may appear on these lines. Any number of comments
+may be included in a SELEX file, and at any point.
+
+\item
+Lines of data consist of a name followed by a sequence. The total
+length of the line must be smaller than 4096 characters.
+
+\item
+Names must be a single word. Any non-whitespace characters are
+accepted.  No spaces are tolerated in names: names MUST be a
+single word. Names must be less than 32 characters long.
+
+\item In the sequence, any of the characters \verb+-_.+ or a space are
+recognized as gaps. Any other characters are interpreted as sequence.
+Sequence is case-sensitive. There is a common assumption by my
+software that upper-case symbols are used for consensus (match)
+positions and lower-case symbols are used for inserts. This language
+of ``match'' versus ``insert'' comes from the hidden Markov model
+formalism \cite{Krogh94}. To almost all of my software, this isn't
+important, and it immediately converts the sequence to all upper-case
+after it's read.
+
+\item
+Multiple different sequences are grouped in a block of data lines.
+Blocks are separated by blank lines. No blank lines are tolerated
+between the sequence lines in a block. Each block in a multi-block
+file of a long alignment must have its sequences in the same order in
+each block. The names are checked to verify that this is the case; if
+not, only a warning is generated. (In manually constructed files, some
+users may wish to use shorthand names in subsequent blocks after an
+initial block with full names -- but this isn't recommended.)
+\end{enumerate}
+
+\section{Stockholm, the recommended multiple sequence alignment format}
+
+While we recommend a community standard format (FASTA) for unaligned
+sequence files, the recommended multiple alignment file format is not
+a community standard.  The Pfam Consortium developed a format (based
+on extended SELEX) called ``Stockholm format''.  The reasons for this
+are two-fold. First, there really is no standard accepted format for
+multiple sequence alignment files, so we don't feel guilty about
+inventing a new one. Second, the formats of popular multiple alignment
+software (e.g. CLUSTAL, GCG MSF, PHYLIP) do not support rich
+documentation and markup of the alignment.  Stockholm format was
+developed to support extensible markup of multiple sequence
+alignments, and we use this capability extensively in both RNA work
+(with structural markup) and the Pfam database (with extensive use of
+both annotation and markup).
+
+\subsection{A minimal Stockholm file}
+\begin{verbatim}
+# STOCKHOLM 1.0
+
+seq1  ACDEF...GHIKL
+seq2  ACDEF...GHIKL
+seq3  ...EFMNRGHIKL
+
+seq1  MNPQTVWY
+seq2  MNPQTVWY
+seq3  MNPQT...
+
+\end{verbatim}
+
+The simplest Stockholm file is pretty intuitive, easily generated in a
+text editor. It is usually easy to convert alignment formats into a
+``least common denominator'' Stockholm format. For instance, SELEX,
+GCG's MSF format, and the output of the CLUSTALV multiple alignment
+program are all similar interleaved formats.
+
+The first line in the file must be \verb+# STOCKHOLM 1.x+, where
+\verb+x+ is a minor version number for the format specification
+(and which currently has no effect on my parsers). This line allows a
+parser to instantly identify the file format.
+
+In the alignment, each line contains a name, followed by the aligned
+sequence. A dash or period denotes a gap. If the alignment is too long
+to fit on one line, the alignment may be split into multiple blocks,
+with blocks separated by blank lines. The number of sequences, their
+order, and their names must be the same in every block. Within a given
+block, each (sub)sequence (and any associated \verb+#=GR+ and
+\verb+#=GC+ markup, see below) is of equal length, called the
+\textit{block length}. Block lengths may differ from block to block;
+the block length must be at least one residue, and there is no
+maximum.  
+
+Other blank lines are ignored. You can add comments to the file on
+lines starting with a \verb+#+.
+
+All other annotation is added using a tag/value comment style. The
+tag/value format is inherently extensible, and readily made
+backwards-compatible; unrecognized tags will simply be ignored. Extra
+annotation includes consensus and individual RNA or protein secondary
+structure, sequence weights, a reference coordinate system for the
+columns, and database source information including name, accession
+number, and coordinates (for subsequences extracted from a longer
+source sequence) See below for details.
+
+\subsection{Syntax of Stockholm markup}
+
+There are four types of Stockholm markup annotation, for per-file,
+per-sequence, per-column, and per-residue annotation:
+
+\begin{wideitem}
+\item {\emprog{#=GF <tag> <s>}}
+	Per-file annotation. \prog{<s>} is a free format text line
+	of annotation type \prog{<tag>}. For example, \prog{#=GF DATE
+	April 1, 2000}. Can occur anywhere in the file, but usually
+	all the \prog{#=GF} markups occur in a header.
+
+\item {\emprog{#=GS <seqname> <tag> <s>}}
+	Per-sequence annotation. \prog{<s>} is a free format text line
+	of annotation type \prog{tag} associated with the sequence
+	named \prog{<seqname>}. For example, \prog{#=GS seq1
+	SPECIES_SOURCE Caenorhabditis elegans}. Can occur anywhere
+	in the file, but in single-block formats (e.g. the Pfam
+	distribution) will typically follow on the line after the
+	sequence itself, and in multi-block formats (e.g. HMMER
+	output), will typically occur in the header preceding the
+	alignment but following the \prog{#=GF} annotation.
+
+\item {\emprog{#=GC <tag> <...s...>}
+	Per-column annotation. \prog{<...s...>} is an aligned text line
+	of annotation type \prog{<tag>}.
+        \verb+#=GC+ lines are
+	associated with a sequence alignment block; \prog{<...s...>}
+	is aligned to the residues in the alignment block, and has
+	the same length as the rest of the block.
+	Typically \verb+#=GC+ lines are placed at the end of each block.
+
+\item {\emprog{#=GR <seqname> <tag> <.....s.....>}
+	Per-residue annotation. \prog{<...s...>} is an aligned text line
+	of annotation type \prog{<tag>}, associated with the sequence
+	named \prog{<seqname>}. 
+	\verb+#=GR+ lines are 
+	associated with one sequence in a sequence alignment block; 
+	\prog{<...s...>}
+	is aligned to the residues in that sequence, and has
+	the same length as the rest of the block.
+	Typically
+        \verb+#=GR+ lines are placed immediately following the
+	aligned	sequence they annotate.
+\end{wideitem}
+
+\subsection{Semantics of Stockholm markup}
+
+Any Stockholm parser will accept syntactically correct files, but is
+not obligated to do anything with the markup lines. It is up to the
+application whether it will attempt to interpret the meaning (the
+semantics) of the markup in a useful way. At the two extremes are the
+Belvu alignment viewer and the HMMER profile hidden Markov model
+software package.
+
+Belvu simply reads Stockholm markup and displays it, without trying to
+interpret it at all. The tag types (\prog{#=GF}, etc.) are sufficient
+to tell Belvu how to display the markup: whether it is attached to the
+whole file, sequences, columns, or residues.
+
+HMMER uses Stockholm markup to pick up a variety of information from
+the Pfam multiple alignment database. The Pfam consortium therefore
+agrees on additional syntax for certain tag types, so HMMER can parse
+some markups for useful information. This additional syntax is imposed
+by Pfam, HMMER, and other software of mine, not by Stockholm format
+per se. You can think of Stockholm as akin to XML, and what my
+software reads as akin to an XML DTD, if you're into that sort of
+structured data format lingo.
+
+The Stockholm markup tags that are parsed semantically by my software
+are as follows:
+
+\subsubsection{Recognized #=GF annotations}
+\begin{wideitem}
+\item [\emprog{ID  <s>}] 
+	Identifier. \emprog{<s>} is a name for the alignment;
+	e.g. ``rrm''. One word. Unique in file.
+
+\item [\emprog{AC  <s>}]
+	Accession. \emprog{<s>} is a unique accession number for the
+	alignment; e.g. 
+	``PF00001''. Used by the Pfam database, for instance. 
+	Often a alphabetical prefix indicating the database
+	(e.g. ``PF'') followed by a unique numerical accession.
+	One word. Unique in file. 
+	
+\item [\emprog{DE  <s>}]
+	Description. \emprog{<s>} is a free format line giving
+	a description of the alignment; e.g.
+	``RNA recognition motif proteins''. One line. Unique in file.
+
+\item [\emprog{AU  <s>}]
+	Author. \emprog{<s>} is a free format line listing the 
+	authors responsible for an alignment; e.g. 
+	``Bateman A''. One line. Unique in file.
+
+\item [\emprog{GA  <f> <f>}]
+	Gathering thresholds. Two real numbers giving HMMER bit score
+	per-sequence and per-domain cutoffs used in gathering the
+	members of Pfam full alignments. See Pfam and HMMER
+	documentation for more detail.
+	
+\item [\emprog{NC  <f> <f>}]
+	Noise cutoffs. Two real numbers giving HMMER bit score
+	per-sequence and per-domain cutoffs, set according to the
+	highest scores seen for unrelated sequences when gathering
+	members of Pfam full alignments. See Pfam and HMMER
+	documentation for more detail.
+
+\item [\emprog{TC  <f> <f>}]
+	Trusted cutoffs. Two real numbers giving HMMER bit score
+	per-sequence and per-domain cutoffs, set according to the
+	lowest scores seen for true homologous sequences that
+	were above the GA gathering thresholds, when gathering
+	members of Pfam full alignments. See Pfam and HMMER
+	documentation for more detail.
+\end{wideitem}
+
+\subsection{Recognized #=GS annotations}
+
+\begin{wideitem}
+\item [\emprog{WT  <f>}]
+	Weight. \emprog{<f>} is a positive real number giving the
+	relative weight for a sequence, usually used to compensate
+	for biased representation by downweighting similar sequences.	
+	Usually the weights average 1.0 (e.g. the weights sum to
+	the number of sequences in the alignment) but this is not
+	required. Either every sequence must have a weight annotated, 
+	or none	of them can.  
+
+\item [\emprog{AC  <s>}]
+	Accession. \emprog{<s>} is a database accession number for 
+	this sequence. (Compare the \prog{#=GF AC} markup, which gives
+	an accession for the whole alignment.) One word. 
+	
+\item [\emprog{DE  <s>}]
+	Description. \emprog{<s>} is one line giving a description for
+	this sequence. (Compare the \prog{#=GF DE} markup, which gives
+	a description for the whole alignment.)
+\end{wideitem}
+
+
+\subsection{Recognized #=GC annotations}
+
+\begin{wideitem}
+\item [\emprog{RF}]
+	Reference line. Any character is accepted as a markup for a
+	column. The intent is to allow labeling the columns with some
+	sort of mark.
+	
+\item [\emprog{SS_cons}]
+	Secondary structure consensus. For protein alignments,
+	DSSP codes or gaps are accepted as markup: [HGIEBTSCX.-_], where
+	H is alpha helix, G is 3/10-helix, I is p-helix, E is extended
+	strand, B is a residue in an isolated b-bridge, T is a turn, 
+	S is a bend, C is a random coil or loop, and X is unknown
+	(for instance, a residue that was not resolved in a crystal
+	structure). For RNA alignments
+	the symbols \verb+>+ and \verb+<+ are
+	used for base pairs (pairs point at each other).  \verb-+- indicate
+	definitely single-stranded positions, and any gap symbol indicates
+	unassigned bases or single-stranded positions.  This description
+	roughly follows \cite{Konings89}. 
+	RNA pseudoknots are represented by alphabetic characters, with upper
+	case letters representing the 5' side of the helix and lower case
+	letters representing the 3' side. Note that this limits the
+	annotation to a maximum of 26 pseudoknots per sequence.
+	
+
+\item [\emprog{SA_cons}]
+	Surface accessibility consensus. 0-9, gap symbols, or X are
+	accepted as markup. 0 means <10\% accessible residue surface
+	area, 1 means <20\%, 9 means <100\%, etc. X means unknown
+	structure.
+\end{wideitem}
+
+\subsection{Recognized #=GR annotations}
+
+\begin{wideitem}
+\item [\emprog{SS}]
+	Secondary structure consensus. See \prog{#=GC SS_cons} above.
+\item [\emprog{SA}]
+	Surface accessibility consensus. See \prog{#=GC SA_cons} above.
+\end{wideitem}

+\section{GSI format}
+
+{\tt GSI} (``generic sequence index'') is a format for indexing
+sequence databases.  Database retrieval programs such as {\tt sfetch}
+can read GSI files when they are available to enable fast retrieval of
+a sequence from large databases.
+
+GSI files are created from sequence databases by Perl scripts.
+Scripts are currently provided for indexing GenBank, SwissProt,
+GenPept, FASTA, and PIR formatted databases.
+
+\subsection {GSI programmatic details}
+
+A single GSI file indexes one or more files in a sequence database.
+It is a binary file consisting of a number of fixed-length records.
+There are three types of records: one header record, one file record
+for every file in the database, and one keyword record for every
+sequence retrieval key. (The retrieval key is usually the sequence
+name, but may also be a database accession number.) 
+
+Every GSI record is 38 bytes long and contains three fields: 32 bytes
+of text (31 bytes plus a trailing NUL byte), a 2 byte network short,
+and a 4 byte network long. (``Network short'' and ``network long''
+refer to portable integer variables of fixed size and byte order. See
+Perl manuals for a few more details.)
+
+The first record is a header.  It contains a short identifying text
+string (``GSI''), then the number of files indexed ({\tt nfiles}), and
+the number of keywords indexed ({\tt nkeys}).
+
+The next {\tt nfiles} records (records 1..{\tt nfiles}) map file
+numbers onto file names. The three fields are \verb+<filename> <file
+number> <file format>+. These records must be in numerical order
+according to their file numbers.  Because of the 31-character
+restriction on filename lengths, the sequence files will generally
+have to be in the same directory as the GSI index file. The file
+format number is defined in {\tt squid.h}:
+
+\begin{tabular}{rl}
+0  & Unknown    \\   
+1  & Intelligenetics\\ 
+2  & Genbank\\ 
+4  & EMBL\\ 
+5  & GCG single sequence\\ 
+6  & Strider        \\ 
+7  & FASTA\\ 
+8  & Zuker\\ 
+9  & Idraw\\ 
+12 & PIR\\ 
+13 & Raw\\ 
+14 & SQUID\\ 
+16 & GCG data library \\ 
+101& Stockholm alignment\\
+102& SELEX alignment\\
+103& GCG MSF alignment\\
+104& Clustal alignment\\
+105& A2M (aligned FASTA) alignment\\
+106& Phylip\\
+\end{tabular}
+
+The remaining records ({\tt nfiles}+1..{\tt nfiles+nkeys}) are for
+mapping keys onto files and disk offsets. The three fields are
+\verb+<keyword> <file number> <disk offset>+. These records must be
+sorted in alphabetic order by their retrieval keys, because the
+function GSIGetOffset() locates a keyword in the index file by a
+binary search.
+
+\subsection{Relevant functions}
+\begin{description}
+\item[GSIOpen()] 
+ 	Opens a GSI index file.
+\item[GSIGetRecord()]
+ 	Gets three fields from the current record.
+\item[GSIGetOffset()] 
+      Looks up a keyword in a GSI index and returns a filename,
+      file format, and disk offset in the file.
+\item[SeqfilePosition()] 
+      Repositions an open sequence file to a given disk offset.
+\item[GSIClose()]
+      Closes an open GSI index file.

+\section{ SELEX alignment file format }
+
+\subsection{ Example of a simple SELEX format file}
+
+\begin{verbatim}
+# Example selex file
+
+seq1     ACGACGACGACG.
+seq2     ..GGGAAAGG.GA
+seq3     UUU..AAAUUU.A
+
+seq1  ..ACG
+seq2  AAGGG
+seq3  AA...UUU
+\end{verbatim}
+
+SELEX is an interleaved multiple alignment format that evolved as an
+intuitive format.  SELEX files are easy to write and manipulate
+manually with a text editor.  It is usually easy to convert other
+alignment formats into SELEX format; the output of the CLUSTALV
+multiple alignment program and GCG's MSF format are similar
+interleaved formats. Because it evolved to accomodate different user
+input styles, it is very tolerant of various inconsistencies such as
+different gap symbols, varying line lengths, etc.
+
+As the format evolved, more features have been added. To maintain
+compatibility with past alignment files, the new features are added
+using a reserved comment style. These extra features are usually
+maintained by automated SELEX-generating software, such as the {\tt
+koala} sequence alignment editor or my {\tt cove} and {\tt hmm} sequence
+analysis packages. This extra information includes consensus and
+individual RNA or protein secondary structure, per-sequence weights, a
+reference coordinate system for the columns, and database source
+information including name, accession number, and coordinates (for
+subsequences extracted from a longer source sequence).
+
+\subsection {Specification of a SELEX file}
+
+\begin{enumerate}
+\item
+Any line beginning with a \verb+#=+ as the first two characters is a
+machine ``comment''.  \verb+#=+ comments are reserved for additional
+data about the alignment. Usually these features are maintained by
+software such as the {\tt koala} editor, not by hand.
+
+\item
+All other lines beginning with a \verb+%+ or \verb+#+ as the first
+character is a user comment.  User comments are ignored by all
+software. Any number of comments may be included.
+
+\item
+Lines of data consist of a name followed by a sequence. The total
+length of the line must be smaller than 1024 characters.
+
+\item
+Names must be a single word. Any non-whitespace characters are
+accepted.  No spaces are tolerated in names: names MUST be a
+single word.
+
+\item
+In the sequence, any of the characters \verb+-_.+ or a space are
+recognized as gaps. Gaps are converted to a '.'. Any other characters
+are interpreted as sequence.  Sequence is case-sensitive. There is a
+common assumption by my software that upper-case symbols are used for
+consensus (match) positions and lower-case symbols are used for
+inserts. This language of ``match'' versus ``insert'' comes from the
+hidden Markov model formalism \cite{Krogh94}. To almost all of my
+software, this isn't important, and it immediately converts the
+sequence to all upper-case after it's read.
+
+\item
+Multiple different sequences are grouped in a block of data lines.
+Blocks are separated by blank lines. No blank lines are tolerated
+between the sequence lines in a block. Each block in a multi-block
+file of a long alignment must have its sequences in the same order in
+each block. The names are checked to verify that this is the case; if
+not, only a warning is generated. (In manually constructed files, some
+users may wish to use shorthand names after the first block with full
+names, but this isn't recommended.)
+\end{enumerate}
+
+\subsection {Special comments}
+
+\subsubsection {Secondary structure}
+
+I use one-letter codes to indicate secondary structures. Secondary
+structure strings are aligned to sequence blocks just like additional
+sequences.
+
+For RNA secondary structure, the symbols \verb+>+ and \verb+<+ are
+used for base pairs (pairs point at each other).  \verb-+- indicate
+other single-stranded positions, {\tt .} indicates unassigned bases.
+This description follows \cite{Konings89}.  For protein secondary
+structure, I use {\tt E} to indicate residues in $\beta$-sheet, {\tt
+H} for those in $\alpha$-helix, {\tt L} for those in loops, and {\tt
+.} for unassigned residues.
+
+RNA pseudoknots are represented by alphabetic characters, with upper
+case letters representing the 5' side of the helix and lower case
+letters representing the 3' side. Note that this restricts the
+annotation to a maximum of 26 pseudoknots per sequence.
+
+Lines beginning with \verb+#=SS+ or \verb+#=CS+ are individual or
+consensus secondary structure data, respectively.  \verb+#=SS+
+individual secondary structure lines must immediately follow the
+sequence they are associated with.  There can only be one \verb+#=SS+
+per sequence. \verb+#=CS+ consensus secondary structure predictions
+precede all the sequences in each block. There can only be one
+\verb+#=CS+ per file.
+
+\subsubsection {Reference coordinate system}
+
+Alignments are usually numbered by some reference coordinate system,
+often a canonical molecule. For instance, tRNA positions are numbered
+by reference to the positions of yeast tRNA-Phe.
+
+A line beginning with \verb+#=RF+ preceding the sequences in a block
+gives a reference coordinate system. Any non-gap symbol in the
+\verb+#=RF+ line indicates that sequence positions in its columns are
+numbered. For instance, the \verb+#=RF+ lines for a tRNA alignment
+would have 76 non-gap symbols for the canonical numbered columns; they
+might be the aligned tRNA-Phe sequence itself, or they might be just
+X's.
+
+\subsubsection {Sequence header}
+
+Additional per-sequence information can be placed in a header before
+any blocks appear. These lines, one per sequence and in exactly the
+same order as the sequences appear in the alignment, are formatted
+like \verb+#=SQ <seqname> <weight> <database source name> <database
+accession> <source coordinates as start..stop::original length>
+<description>+.
+
+This information includes a sequence weight (for compensating for
+biased representation of subfamilies of sequences in the alignment);
+source information, if the sequence came from a database, consisting
+of identifier, accession number, and source coordinates; and a
+description of the sequence.
+
+If a \verb+#=SQ+ line is present, all the fields must be present.  If
+no information is available for a field, use '-' for all the fields
+except the source coordinates, which would be given as '0'.
+
+\subsubsection {Author}
+
+The first non-comment, non-blank line of the file may be a \verb+#=AU+
+``author'' line. There is a programmatic interface for
+alignment-generating programs to record a short comment like \verb+11
+November 1993, by Feng-Doolittle v. 2.1.1+, and this comment will be
+recorded on the \verb+#=AU+ line by \verb+WriteSELEX()+.

+\section {SQUID format}
+
+SQUID format is a sequence database format similar to the PIR,
+GenBank, and EMBL formats. The primary difference is that SQUID format
+may optionally contain secondary structure annotation information for
+the sequence. No other sequence format allows secondary structure
+annotation, which is why SQUID format became necessary.
+
+An example SQUID format file:
+
+\begin{verbatim}
+NAM  DY9990
+SRC  HSTGYA M27547 76..169::196
+DES  Human Tyr-tRNA gene, clone pM6.

+\subsection {Specification of a SQUID file}
+
+\begin{enumerate}
+\item There must be a line of the form \verb+NAM  <sequence name>+.
+
+\item There may be an optional line \verb+SRC <id> <acc>
+<start>..<stop>::<olen>+, which specified a database source for this
+sequence, giving the database identifier (name), accession number,
+start and end position in the database sequence, and the original
+length of the database sequence, respectively.  If a \verb+SRC+ line
+is present, all of these values must be specified.  If any values are
+unknown, they may be set to \verb+-+ in the case of \verb+<id>+ and
+\verb+<acc>+ and \verb+0+ in the case of \verb+<start>+, \verb+<stop>,
+and \verb+<olen>+, and in these cases the values will be ignored.
+
+\item There may be an optional line  \verb+DES <description>+ giving
+a one-line description of the sequence.
+
+\item There must be a line of the form \verb-SEQ +SS- or \verb-SEQ-.
+If the line contains \verb-+SS-, it means that the record contains
+secondary structure annotation interleaved with the sequence.
+
+\item The sequence (and optional structure) immediately follow. There may be
+optional numbering either before or after the sequence. The number of
+characters per line is unimportant. Spaces and tabs are ignored.
+There must be no non-numeric non-space characters on any lines except
+sequence or structure annotation characters. Structure annotation is
+fairly free-form; any alphabetic character or character in the set
+\verb/_.-*?<>{}[]()!@#$%^&=+;:'|`~"\/ is accepted. There must
+be one such character for every sequence character (preferably aligned
+to the sequence, but in fact this is not checked for). Note that
+spaces in the secondary structure annotation are not permitted,
+except where they are aligned to gaps in the sequence.
+
+\item Sequence records are separated by a line of the form \verb-++-.

+\section{SSI format}
+
+SSI format (Sequence/Subsequence Index format) indexes flatfile
+databases by names and/or accessions, enabling fast retrieval.
+
+An SSI index is a binary file that stores sequence names or accessions
+as \emph{keys} that it can look up rapidly. It differentiates between
+\emph{primary keys} and \emph{secondary keys}.  There is one and only
+one primary key per sequence. There can be more than one secondary key
+per sequence. Both primary and secondary keys must be unique
+identifiers (no two records have the same key). A program (like
+HMMER's distributed PVM implementation) that needs to step through
+each sequence one at a time can refer to the list of primary keys. A
+program solely concerned with flexible sequence retrieval (such as
+SQUID's \prog{sfetch}) might consult an SSI index with accessions as
+primary keys, and names as secondary keys.
+
+A single SSI file can index multiple sequence data files. This allows
+indexing multifile databases (e.g. Genbank flatfile distributions).
+
+The SSI format is relatively simple and may prove useful for other
+indexing tasks besides sequence names. HMMER uses SSI format to index
+HMM files.
+
+\subsection{Special features of SSI}
+
+SSI superceded 1994's GSI format after human genome sequence files
+started exceeding 2 GB filesystem limitations, and after problems in
+the HMMER PVM implementation had to be hacked around. SSI has the
+following additional features compared to GSI.
+
+\begin{description}
+\item[Separate primary key section] 
+Primary keys are set apart in a separate section, enabling programs to
+step through a guaranteed one-to-one mapping of keys to sequences.  A
+secondary key section adds many-to-one mapping of keys to sequences.
+
+\item[Arbitrary filename and key lengths]
+File name lengths and key name lengths are effectively unlimited. 
+
+\item[64-bit indexing]
+For sequence files exceeding 2GB, on architectures that support 64-bit
+filesystems (such as IRIX, Solaris, Tru64 UNIX, FreeBSD...), SSI
+supports 64-bit indexing; depending on the system, file sizes may 
+theoretically be allowed to range up to millions of terabytes.
+
+\item[Fast subsequence extraction]
+SSI can be used to greatly accelerate \emph{subsequence} extraction
+from very long sequences (example: human chromosome contigs). The
+sequence file must meet certain formatting conditions for this to
+work; see below for details.
+\end{description}
+
+\subsection{SSI API in SQUID}
+
+\subsubsection{Functions for using a SSI index file:}
+
+\begin{sreapi}
+\item[int SSIOpen(char *filename, SSIFILE **ret\_sfp)]
+
+Opens the SSI index file \prog{filename} and returns a \prog{SSIFILE
+*} stream through \prog{ret\_sfp}. Returns 0 on success, nonzero on
+failure. The caller must eventually close this stream using
+\prog{SSIClose()}.  More than one index can be open at once.
+
+Error codes:\\
+\begin{tabular}{ll}
+\prog{SSI\_ERR\_NOFILE}   & failed to open file; doesn't exist or not readable\\
+\prog{SSI\_ERR\_BADMAGIC} & not a SSI file \\
+\prog{SSI\_ERR\_NO64BIT}  & it has 64-bit offsets, and we can't support that\\
+\prog{SSI\_ERR\_FORMAT}   & file appears to be corrupted\\
+\prog{SSI\_ERR\_MALLOC}   & malloc failed \\
+\end{tabular}
+
+\item[int SSIGetOffsetByName(SSIFILE *sfp, char *key, int *ret\_fh, SSIOFFSET *ret\_offset)]
+
+Looks up the string \prog{key} in the open index \prog{sfp}.
+\prog{key} can be either a primary or secondary key. If \prog{key} is
+found, \prog{*ret\_fh} contains a unique handle on the file
+that contains {key} (suitable for an \prog{SSIFileInfo()} call, or for
+comparison to the handle of the last file that was opened for
+retrieval), and \prog{offset} is filled in with the offset in that
+file. Returns 0 on success, non-zero on error.
+
+Error codes:\\
+\begin{tabular}{ll}
+\prog{SSI\_ERR\_NO\_SUCH\_KEY} & key not found \\
+\prog{SSI\_ERR\_NODATA}        & fread() failed, file appears to be corrupted\\
+\end{tabular}
+
+\item[int SSIGetOffsetByNumber(SSIFILE *sfp, int nkey, int
+*ret\_fh, SSIOFFSET *offset)]
+
+Retrieves information for primary key number \prog{nkey}.  \prog{nkey}
+ranges from 0..\prog{nprimary-1}. When the key is found,
+\prog{*ret\_fh} contains a unique handle on the file that
+contains {key} (suitable for an SSIFileInfo() call, or for comparison
+to the handle of the last file that was opened for retrieval), and
+\prog{offset} is filled in with the offset in that file. Returns 0 on
+success, non-zero on error.
+
+Error codes:\\
+\begin{tabular}{ll}
+\prog{SSI\_ERR\_SEEK\_FAILED}  & failed to reposition in index file\\
+\prog{SSI\_ERR\_NO\_SUCH\_KEY} & key not found \\
+\prog{SSI\_ERR\_NODATA}        & fread() failed, file appears to be corrupted\\
+\end{tabular}
+
+\item[int SSIGetSubseqOffset(SSIFILE *sfp, char *key, int
+requested\_start,  int *ret\_fh,
+SSIOFFSET *record\_offset, SSIOFFSET *data\_offset, int *ret\_actual\_start)]
+
+Implements \prog{SSI\_FAST\_SUBSEQ}. 
+
+Looks up the string \prog{key} in the open index \prog{sfp}, and
+asks for the nearest offset to a subsequence starting at position
+\prog{requested\_start} in the sequence (numbering the sequence 1..L).
+\prog{key} can be either a primary or secondary key. If \prog{key} is
+found, \prog{*ret\_fh} contains a unique handle on the file that
+contains {key} (suitable for an SSIFileInfo() call, or for comparison
+to the handle of the last file that was opened for retrieval);
+\prog{record\_offset} contains the disk offset to the start of the
+record; \prog{data\_offset} contains the disk offset either exactly at
+the requested residue, or at the start of the line containing the
+requested residue; \prog{ret\_actual\_start} contains the coordinate
+(1..L) of the first valid residue at or after
+\prog{data\_offset}. \prog{ret\_actual\_start} is $\leq$
+\prog{requested\_start}.  Returns 0 on success, non-zero on failure.
+
+Error codes:\\
+\begin{tabular}{ll}
+\prog{SSI\_ERR\_NO\_SUBSEQS}   & this file or key doesn't allow subseq lookup\\
+\prog{SSI\_ERR\_NO\_SUCH\_KEY} & key not found \\
+\prog{SSI\_ERR\_RANGE}         & the requested\_start is out of bounds\\
+\prog{SSI\_ERR\_NODATA}        & fread() failed, file appears to be corrupted\\
+\end{tabular}
+
+\item[int SSISetFilePosition(FILE *fp, SSIOFFSET *offset]
+
+Uses \prog{offset} to sets the file position for \prog{fp} (usually an
+open sequence file) relative to the start of the file.  Hides the
+details of system-dependent shenanigans necessary for file positioning
+in large ($>2$ GB) files. Behaves just like \prog{fseek(fp, offset,
+SEEK\_SET)} for 32 bit offsets and $<2$ GB files. Returns 0 on
+success, nonzero on error.
+
+Error codes:\\
+\begin{tabular}{ll}
+\prog{SSI\_ERR\_SEEK\_FAILED}  & failed to reposition the file\\
+\end{tabular}
+
+\item[int SSIFileInfo(SSIFILE *sfp, int fh, char **ret\_filename, int *ret\_format)]
+
+Given a file handle \prog{fh} in an open index file \prog{sfp},
+retrieve file name \prog{ret\_filename} and the file format
+\prog{ret\_format}.  \prog{ret\_filename} is a pointer to a string
+maintained internally by \prog{sfp}. It should not be free'd;
+\prog{SSIClose(sfp)} will take care of it.
+
+Error codes:\\
+\begin{tabular}{ll}
+\prog{SSI\_ERR\_BADARG}  & no such file n\\
+\end{tabular}
+
+\item[void SSIClose(SSIFILE *sfp)]
+
+Close an open \prog{SSIFILE *}.
+\end{sreapi}
+
+\subsubsection{Skeleton example code for using a SSI index file:} 
+
+\small\begin{verbatim}

+\end{verbatim}\normalsize
+
+\subsubsection{Functions for creating a SSI index file:}
+
+\begin{sreapi}
+\item[int SSIRecommendMode(char *file)]
+
+Examines the file and determines whether it should be indexed with
+large file support or not; returns \prog{SSI\_OFFSET\_I32} for most
+files, \prog{SSI\_OFFSET\_I64} for large files, or -1 on failure.
+
+\item[SSIINDEX *SSICreateIndex(int mode)]
+
+Creates and initializes a SSI index structure. Sequence file offset
+type to be used is specified by \prog{mode}, which may be either
+\prog{SSI\_OFFSET\_I32} or \prog{SSI\_OFFSET\_I64}.  Returns a
+pointer to the new structure, or NULL on failure. The caller must free
+this structure with \prog{SSIFreeIndex()} when done.
+
+\item[int SSIGetFilePosition(FILE *fp, int mode, SSIOFFSET *ret\_offset)]
+
+Fills \prog{ret\_offset} with the current disk offset of \prog{fp},
+relative to the start of the file.  {mode} is the type of offset to
+use; it must be either \prog{SSI\_OFFSET\_I32} or
+\prog{SSI\_OFFSET\_I64}. Returns 0 on success, non-zero on error.
+
+Error codes:\\
+\begin{tabular}{ll}
+\prog{SSI\_ERR\_NO64BIT}       & 64-bit mode unsupported on this system\\
+\prog{SSI\_ERR\_TELL\_FAILED}  & failed to determine position in file\\
+\end{tabular}
+
+\item[int SSIAddFileToIndex(SSIINDEX *g, char *filename, int fmt,
+int *ret\_fh)]
+
+Adds the sequence file \prog{filename}, which is known to be in format
+\prog{fmt}, to the index \prog{g}. Creates and returns a unique
+filehandle \prog{ret\_fh} for associating primary keys with this file
+using \prog{SSIAddPrimaryKeyToIndex()}. Returns 0 on success, non-zero
+on failure.
+
+Error codes:\\
+\begin{tabular}{ll}
+\prog{SSI\_ERR\_TOOMANY\_FILES}  & exceeded file number limit\\
+\prog{SSI\_ERR\_MALLOC}          & a malloc() failed\\
+\end{tabular}
+
+\item[int SSISetFileForSubseq(SSIINDEX *g, int fh, int bpl, int rpl)]
+
+Set \prog{SSI\_FAST\_SUBSEQ} for the file indicated by filehandle
+\prog{fh} in the index \prog{g}, setting parameters \prog{bpl} and
+\prog{rpl} to the values given. \prog{bpl} is the number of bytes per
+sequence data line.  \prog{rpl} is the number of residues per sequence
+data line.  Caller must be sure that \prog{bpl} and \prog{rpl} do not
+change on any line of any sequence record in the file (except for the
+last data line of each record). If this is not the case in this file,
+\prog{SSI\_FAST\_SUBSEQ} will not work, and this routine should not be
+called. Returns 0 on success, non-zero on failure.
+
+\item[int SSIAddPrimaryKeyToIndex(SSIINDEX *g, char *key, int
+fh, SSIOFFSET *r\_off, SSIOFFSET *d\_off, int L)]
+
+Puts a primary key \prog{key} in the index \prog{g}, while telling the
+index that this primary key is in the file associated with filehandle
+\prog{fh} and its record starts at position \prog{r\_off} in that
+file.
+
+\prog{d\_off} and \prog{L} are optional; they may be left unset by
+passing NULL and 0, respectively. (If one is provided, both must be
+provided.)  If they are provided, \prog{d\_off} gives the position of
+the first line of sequence data in the record, and \prog{L} gives
+the length of the sequence in residues. They are used when
+\prog{SSI\_FAST\_SUBSEQ} is set for the sequence file. If
+\prog{SSI\_FAST\_SUBSEQ} is not set for the file, \prog{d\_off} and
+\prog{L} will be ignored even if they are available, so it doesn't
+hurt for the indexing program to provide them; typically it won't know
+whether it's safe to set \prog{SSI\_FAST\_SUBSEQ} for the whole file
+until the whole file has been read and every key has already been
+added to the index.
+
+Through \prog{ret\_kh} it provides a ``handle'' - a unique
+identifier for the primary key - that any subsequent calls to
+\prog{SSIAddSecondaryKeyToIndex()} will use to associate one or more
+secondary keys with this primary key.
+
+Returns 0 on success, non-zero on error.
+
+Error codes:\\
+\begin{tabular}{ll}
+\prog{SSI\_ERR\_TOOMANY\_KEYS}  & exceeded primary key limit\\
+\prog{SSI\_ERR\_TOOMANY\_FILES} & filenum exceeds file limit\\
+\prog{SSI\_ERR\_MALLOC}         & a malloc() failed\\
+\end{tabular}
+
+
+\item[int SSIAddSecondaryKeyToIndex(SSIINDEX *g, char *key, char *pkey)]
+
+Puts a secondary key \prog{key} in the index \prog{g}, associating it
+with a primary key \prog{pkey} that has already been added to the index
+by \prog{SSIAddPrimaryKeyToIndex()}.
+Returns 0 on success, non-zero on error.
+
+Error codes:\\
+\begin{tabular}{ll}

+\prog{SSI\_ERR\_MALLOC}         & a malloc() failed\\
+\end{tabular}
+
+
+
+\item[int SSIWriteIndex(char *file, SSIINDEX *g)]
+
+Writes complete index \prog{g} in SSI format to a binary file
+\prog{file}.  Does all overhead of sorting the primary and secondary
+keys, and maintaining the association of secondary keys with primary
+keys during and after the sort. Returns 0 on success, non-zero on
+error.
+
+Error codes:\\
+\begin{tabular}{ll}

+\end{tabular}
+
+
+\item[void SSIFreeIndex(SSIINDEX *g)]
+
+Free an index structure.
+\end{sreapi}
+    
+
+\subsubsection{Other SSI functions:}
+
+\begin{sreapi}
+\item[char *SSIErrorString(int n)] 
+
+Returns a pointer to an internal string corresponding to error
+\prog{n}, a return code from any of the functions in the API that
+return non-zero on error.
+\end{sreapi}
+
+\subsection{Detailed specification of SSI binary format}
+
+There are four sections to the SSI file:
+\begin{sreitems}{\textbf{Secondary keys}}
+\item[\textbf{Header}] 
+Contains a magic number indicating GSI version number, and 
+various information about the number and sizes of things in the index.
+
+\item[\textbf{Files}]
+Contains one or more \emph{file records}, one per sequence file that's
+indexed. These contain information about the individual files.
+
+\item[\textbf{Primary keys}]
+Contains one or more \emph{primary key records}, one per primary key.
+
+\item[\textbf{Secondary keys}]
+Contains one or more \emph{secondary key records}, one per secondary key.
+\end{sreitems}
+
+All numeric quantities are stored as unsigned integers of known size
+in network (bigendian) order, for maximum crossplatform portability of
+the index files. \prog{sqd\_uint16}, \prog{sqd\_uint32}, and
+\prog{sqd\_uint64} are typically typedef'd as \prog{unsigned short},
+\prog{unsigned int}, and \prog{unsigned long long} or \prog{unsigned
+long} at SQUID compile-time. Values may need to be cast to signed
+quantities, so only half of their dynamic range is valid
+(e.g. 0..32,767 for values of type \prog{sqd\_uint16};
+0..2,146,483,647 (2 billion) for \prog{sqd\_uint32}; and 0..9.22e18 (9
+million trillion) for \prog{sqd\_uint64}).  These typedef's are
+handled automatically by the \prog{./configure} script (see
+\prog{squidconf.h.in} before configuration, \prog{squidconf.h} after
+configuration). If necessary, \prog{./configure}'s guess can be
+overridden in \prog{squidconf.h} after configuration.
+
+\subsubsection{Header section}
+
+The header section contains:
+
+\vspace{1em}
+\begin{tabular}{llrr}
+Variable          & Description                              & Bytes      & Type \\\hline
+\prog{magic}      & SSI version magic number.               &  4         & \prog{sqd\_uint32}\\
+\prog{flags}      & Optional behavior flags (see below)      &  4         & \prog{sqd\_uint32}\\
+\prog{nfiles}     & Number of files in file section.         &  2         & \prog{sqd\_uint16}\\
+\prog{nprimary}   & Number of primary keys.                  &  4         & \prog{sqd\_uint32}\\
+\prog{nsecondary} & Number of secondary keys.                &  4         & \prog{sqd\_uint32}\\
+\prog{flen}       & Length of filenames (incl. '\verb+\0+')         &  4         & \prog{sqd\_uint32}\\
+\prog{plen}       & Length of primary key names (incl. '\verb+\0+') &  4         & \prog{sqd\_uint32}\\
+\prog{slen}       & Length of sec. key names (incl. '\verb+\0+')    &  4         & \prog{sqd\_uint32}\\
+\prog{frecsize}   & \# of bytes in a file record             &  4         & \prog{sqd\_uint32}\\
+\prog{precsize}   & \# of bytes in a primary key record      &  4         & \prog{sqd\_uint32}\\
+\prog{srecsize}   & \# of bytes in a sec. key record         &  4         & \prog{sqd\_uint32}\\
+\prog{foffset}    & disk offset, start of file records       &  \dag         & \dag\\
+\prog{poffset}    & disk offset, start of primary key recs   &  \dag         & \dag\\
+\prog{soffset}    & disk offset, start of sec. key records   &  \dag         & \dag\\
+\end{tabular}
+\vspace{1em}
+
+The optional behavior flags are:
+
+\vspace{1em}
+\begin{tabular}{lll}
+Flag             & Value& Note\\ \hline
+\prog{SSI\_USE64}         & $1 \ll 0$ & Large sequence files; all key offsets 64 bit.\\
+\prog{SSI\_USE64\_INDEX}  & $1 \ll 1$ & Large index; GSI file itself uses 64-bit offsets.\\\hline
+\end{tabular}
+\vspace{1em}
+
+The optional behavior flags define whether the SSI file uses large
+file (64-bit) offsets.  This issue is discussed in greater detail
+below (see ``Large sequence files and large indices''). Briefly: if
+\prog{SSI\_USE64} is set, the sequence file is large, and all sequence
+file offsets are 64-bit integers.  If \prog{SSI\_USE64\_INDEX} is
+set, the index file itself is large, and \prog{foffset},
+\prog{poffset}, and \prog{soffset} (that is, all offsets within the
+index file itself, indicated as \dag\ in the above table) are 64-bit
+integers. \footnote{In the current API it is not expected that
+\prog{SSI\_USE64\_INDEX} would ever be set. The current index-writing
+API keeps the entire index in RAM (it has to sort the keys), and would
+presumably have to be modified or replaced to be able to generate very
+large indices.}
+
+The reason to explicitly record various record sizes (\prog{frecsize},
+\prog{precsize}, \prog{srecsize}) and index file positions
+(\prog{foffset}, \prog{poffset}, \prog{soffset}) is to allow future
+extendibility. More fields might be added without breaking older SSI
+parsers.  The format is meant to be both forwards- and
+backwards-compatible.
+
+\subsubsection{File section}
+
+The file section consists of \prog{nfiles} file records. Each record
+is \prog{frecsize} bytes long, and contains:
+
+\vspace{1em}
+\begin{tabular}{llrr}
+Variable & Description                                       & Bytes & Type \\\hline
+\prog{filename} & Name of file (possibly including full path)       & \prog{flen} & char *\\
+\prog{format}   & Format code for file; see squid.h for definitions & 4    & \prog{sqd\_uint32} \\
+\prog{flags}    & Optional behavior flags                           & 4    & \prog{sqd\_uint32} \\
+\prog{bpl}      & Bytes per sequence data line                      & 4    & \prog{sqd\_uint32} \\
+\prog{rpl}      & Residues per sequence data line                   & 4    & \prog{sqd\_uint32} \\\hline
+\end{tabular}
+\vspace{1em}
+
+When a SSI file is written, \prog{frecsize} is equal to the sum of
+the sizes above.  When a SSI file is read by a parser, it is possible
+that \prog{frecsize} is larger than the parser expects, if the parser
+is expecting an older version of the SSI format: additional fields
+may be present, which increases \prog{frecsize}. The parser will only
+try to understand the data up to the \prog{frecsize} it expected to
+see, but still knows the absolutely correct \prog{frecsize} for
+purposes of skipping around in the index file.
+
+Normally the SSI index resides in the same directory as the sequence
+data file(s), so \prog{filename} is relative to the location of the
+SSI index. In the event this is not true, \prog{filename} can contain
+a full path.
+
+\prog{format} is a SQUID sequence file format code; e.g. something like 
+\prog{SQFILE\_FASTA} or \prog{MSAFILE\_STOCKHOLM}. These constants are defined
+in \prog{squid.h}.
+
+Only one possible optional behavior flag is defined:
+
+\vspace{1em}
+\begin{tabular}{lll}
+Flag             & Value& Note\\ \hline
+\prog{SSI\_FAST\_SUBSEQ} & $1 \ll 0$ & Fast subseq retrieval is possible for this file.\\\hline
+\end{tabular}
+\vspace{1em}
+
+When \prog{SSI\_FAST\_SUBSEQ} is set, \prog{bpl} and \prog{rpl} are
+nonzero. They can be used to calculate the offset of subsequence
+positions in the data file. This is described in the optional behavior
+section below.
+
+\subsubsection{Primary key section}
+
+The primary key section consists of \prog{nprimary} records. Each
+record is \prog{precsize} bytes long, and contains:
+
+\vspace{1em}
+\begin{tabular}{llrr}
+Variable   & Description                                 & Bytes      & Type \\\hline
+\prog{key}	   & Key name (seq name, identifier, accession) & \prog{plen}& char *\\
+\prog{fnum}       & File number (0..nfiles-1)                   & 2          & \prog{sqd\_uint16}\\
+\prog{offset1}    & Offset to start of record                   & \ddag      & \ddag \\
+\prog{offset2}    & Offset to start of sequence data            & \ddag      & \ddag \\
+\prog{len}        & Length of data (e.g. seq length, residues)  & 4          & \prog{sqd\_uint32} \\\hline
+\end{tabular} 
+\vspace{1em}
+
+The offsets are sequence file offsets (indicated by \ddag). They are
+4 bytes of type \prog{sqd\_uint32} normally, 8 bytes of type
+\prog{sqd\_uint32} if \prog{SSI\_USE64} is set, and \prog{sizeof(fpos\_t)} 
+bytes of type \prog{fpos\_t} if \prog{SSI\_FPOS\_T} is set.
+
+\prog{offset2} and \prog{len} are only meaningful if \prog{SSI\_FAST\_SUBSEQ}
+is set on this key's file. \prog{offset2} gives the absolute disk
+position of line 0 in the sequence data. \prog{len} is necessary for
+bounds checking in a subsequence retrieval, to be sure we don't try to
+reposition the disk outside the valid data.
+
+\subsubsection{Secondary key section}
+
+The secondary key section consists of \prog{nsecondary} records. Each
+record is \prog{srecsize} bytes long, and contains:
+
+\vspace{1em}
+\begin{tabular}{llrr}
+Variable   & Description                                   & Bytes      & Type \\\hline
+\prog{key}   & Key name (seq name, identifier, accession)  & \prog{slen}& char *\\
+\prog{pkey}  & Primary key                                 &
+\prog{plen}& char *\\\hline
+\end{tabular}
+\vspace{1em}
+
+All data are kept with the primary key records. Secondary keys are
+simply translated to primary keys, then the primary key has to be
+looked up.
+
+\subsection{Optional behaviors}
+
+\subsubsection{Large sequence files and large indices: 64-bit operation}
+
+Normally a SSI index file can be no larger than 2 GB, and can index
+sequence files that are no larger than 2 GB each. This is due to
+limitations in the ANSI C/POSIX standards, which were developed for
+32-bit operating systems and filesystems. Most modern operating
+systems allow larger 64-bit file sizes, but as far as I'm aware (Dec
+2000), there are no standard interfaces yet for working with positions
+(offsets) in large files. On many platforms, SSI can extend to full
+64-bit capabilities, but on some platforms, it cannot. To understand
+the limitations (of SSI, and possibly of my understanding) you need
+to understand some details about what's happening behind the SSI API
+and how I understand C API's to modern 64-bit OS's and hardware.
+
+First, some information on ANSI C APIs for file positioning. ANSI C
+provides the portable functions \prog{fseek()} and \prog{ftell()} for
+manipulating simple offsets in a file. They store the offset in a
+\prog{long} (which ranges up to 2 GB). The Standard says we're allowed
+to do arithmetic on this value if the file is binary. ANSI C also
+provides \prog{fgetpos()} and \prog{fsetpos()} which store file
+positions in an opaque data type called \prog{fpos\_t}. Modern
+operating systems with large file support define \prog{fpos\_t} in a
+way that permits files $>$2 GB. However, \prog{fpos\_t} is an opaque
+type. It has two disadvantages compared to a simple arithmetic type
+like \prog{long}: first, we're not allowed to do arithmetic on it, and
+second, we can't store it in a binary file in an
+architecture-independent manner. We need both features for SSI,
+unfortunately. \footnote{Surely the professional C community has the
+same problem; does \emph{everyone} hack around \prog{fpos\_t}?}
+
+Therefore we have to rely on system dependent features. Most operating
+systems provide a non-compliant library call that returns an
+arithmetic offset. Fully 64-bit systems typically give us a 64-bit
+\prog{off\_t} and functions \prog{ftello()}/\prog{fseeko()} that work
+with that offset.  Many systems provide a ``transitional interface''
+where all normally named functions are 32-bits, but specially named
+64-bit varieties are available: e.g. \prog{off\_t} is 32 bits, but
+\prog{off64\_t} is 64 bits and we have functions \prog{ftello64()} and
+\prog{fseeko64()}. Some systems provide a \prog{ftell64()} and
+\prog{fseek64()} that work on offsets of type \prog{long long}. Many
+popular systems may even provide more than one of these models,
+depending on compiler flags. 
+
+And, unfortunately, some systems provide none of these models (FreeBSD
+for example). There, we will exploit the fact that most systems
+(including FreeBSD) do in fact implement \prog{fpos\_t} as a simple
+arithmetic type, such as an \prog{off\_t}, so we can misuse it.
+
+At compile time, SQUID's \prog{./configure} script tests for the
+system's capabilities for 64-bit file offsets, and configures a
+section in the \prog{squidconf.h} file. (The configuration includes a
+custom autoconf macro, \prog{SQ\_ARITHMETIC\_FPOS\_T()}, to test
+\prog{fpos\_t} and define \prog{ARITHMETIC\_FPOS\_T} if it is.)  Four
+possible 64-bit models are tested in the following order; if one of
+them is possible, it will be used, and the constant
+\prog{HAS\_64BIT\_FILE\_OFFSETS} is set.
+
+\begin{enumerate}
+\item has \prog{ftello()}, \prog{fseeko()}; sizeof(\prog{off\_t}) $= 8$.
+\item has \prog{ftello64()}, \prog{fseeko64()}; sizeof(\prog{off64\_t}) $= 8$.
+\item has \prog{ftell64()}, \prog{fseek64()}
+\item \prog{fpos\_t} is an arithmetic 64-bit type; (mis)use
+\prog{fgetpos()}, \prog{fsetpos()}.
+\end{enumerate}
+
+
+
+\subsubsection{Fast subsequence retrieval}
+
+In some files (notably vertebrate chromosome contigs) the size of each
+sequence is large. It may be slow to extract a subsequence by first
+reading the whole sequence into memory -- or even prohibitive, if the
+sequence is so large that it can't be stored in memory.
+
+If the sequence data file is very consistently formatted so that each
+line in each record (except the last one) is of the same length, in
+both bytes and residues, we can determine a disk offset of the start
+of any subsequence by direct calculation.
+For example, a simple well-formatted FASTA
+file with 50 residues per line would have 51 bytes per sequence line
+(counting the '\verb+\0+') (\prog{bpl}=51, \prog{rpl}=50). Position $i$ in a sequence
+$1..L$ will be on line $l = (i-1)/\mbox{\prog{rpl}}$, and line $l$ starts at
+disk offset $l * \mbox{\prog{bpl}}$ relative to the start of the sequence
+data. If there are no nonsequence characters in the data line except
+the terminal '\verb+\0+' (which is true iff \prog{bpl} = \prog{rpl}+1 and 1 residue = 1
+byte), position $i$ can be precisely found:
+
+\[
+\mbox{relative offset of residue $i$} =
+\left((i-1)/\mbox{\prog{rpl}}\right)*\mbox{\prog{bpl}} + (i-1) \% \mbox{ \prog{rpl}}
+\]
+
+Even for sequence data lines with extra characters (e.g. spaces,
+coordinates, whatever), fast subsequence retrieval is possible; a
+parser can be positioned at the beginning of the appropriate line $l$,
+which starts at residue $(l*\mbox{\prog{rpl}}) + 1$, and it can start reading
+from there (e.g. the line that $i$ is on) rather than the beginning of
+the whole sequence record.
+
+The program that creates the index is responsible for determining if
+\prog{bpl} and \prog{rpl} are consistent throughout a file; if so, it
+may set the \prog{SSI\_FAST\_SUBSEQ} flag for the file. Then any record
+whose primary key carries the optional data offset (\prog(offset2))
+and sequence length data is available for subsequence position
+calculations by \prog{SSIGetSubseqOffset()}.

+Brief installation instructions for squid
+SRE, Tue Jul 25 08:52:03 2000
+________________________________________________________________
+
+For a source distribution (example: squid-1.7.tar.gz), on a UNIX system:
+
+   gunzip squid-1.7.tar.gz   Uncompresses the archive.
+   tar xf squid-1.7.tar      Unpacks the archive. 
+                             (makes a new directory, squid-1.7)
+   cd squid-1.7              Moves into the distribution toplevel directory.
+   ./configure               Configures the software for your system.
+   make                      Builds the binaries. 
+   make install              Installs the software. (You may need to be root.)
+   make clean                Cleans up.
+ 
+The default is to install into /usr/local/bin and other /usr/local
+subdirectories. If this isn't what you want, edit the top of the
+Makefile; instructions are provided there for changing the
+installation paths.
+
+Any failure to install on a UNIX system is a bug. Please report it.
+
+Man pages are provided for some programs; see Man/ subdirectory.

+### Installation points
+###
+# For simple installations, just make sure ${prefix} is set correctly:
+# default is /usr/local.
+#
+# For heterogenous computing environments, also
+# set ${exec_prefix}, which gives you some flexibility 
+# for installing architecture dependent files (e.g. the programs).
+#
+# It's less likely that you'll need to set the individual
+# variables BINDIR, MANDIR, etc., but they're there if you need 'em.
+#
+# The (simple) default configuration installs as follows:
+#    prefix = /usr/local     
+#         executables in   /usr/local/bin
+#         man pages in     /usr/local/man/man1
+#         header files in  /usr/local/include
+#         libsquid.a in    /usr/local/lib
+#         scripts in       /usr/local/bin
+#
+# The St. Louis configuration, an example of a heterogenous 
+# computing environment, installs by setting:
+#    prefix      = /usr/seshare/
+#    exec_prefix = /usr/seshare/`uname`
+#
+# on a Linux platform, for instance, this results in:
+#         executables in   /usr/seshare/Linux/bin
+#         man pages in     /usr/seshare/man
+#         header files in  /usr/seshare/include
+#         libsquid.a in    /usr/seshare/Linux/lib

+
+.SH SYNOPSIS
+.B alistat
+.I [options]
+.I alignfile
+
+.SH DESCRIPTION
+
+.B alistat
+reads a multiple sequence alignment from the file
+.I alignfile
+in any supported format (including SELEX, GCG MSF, and
+CLUSTAL), and shows a number of simple statistics about it.
+These statistics include the name of the format,
+the number of sequences, the total number of residues,
+the average and range of the sequence lengths, the
+alignment length (e.g. including gap characters).
+
+.PP
+Also shown are some percent identities. A percent
+pairwise alignment identity is defined as
+.I (idents / MIN(len1, len2))
+where 
+.I idents
+is the number of exact identities
+and 
+.I len1, len2
+are the unaligned lengths of the two
+sequences. The "average percent identity",
+"most related pair", and "most unrelated pair"
+of the alignment are the average, maximum, and
+minimum of all 
+(N)(N-1)/2 pairs, respectively.
+The "most distant seq" is calculated by finding
+the maximum pairwise identity (best relative) for all N sequences,
+then finding the minimum of these N numbers (hence, 
+the most outlying sequence).
+
+.SH OPTIONS
+
+.TP
+.B -a 
+Show additional verbose information: a table with one line per
+sequence showing name, length, and its highest and lowest pairwise
+identity. These lines are prefixed with a * character to enable
+easily 
+.BR grep' ing
+them out and sorting them. For example,
+.I alistat -a foo.slx | grep "*" | sort -n +3 
+gives a ranked list of the most distant sequences
+in the alignment. 
+Incompatible with the

+option.
+
+.TP 
+.B -f 
+Fast; use a sampling method to estimate the average %id.
+When this option is chosen,

+which the full (N)(N-1) calculation of all pairs would
+be prohibitive (e.g. Pfam's GP120 alignment, with over

+.SH NAME

+sfetch - get a sequence from a flatfile database.
+
+.SH SYNOPSIS
+.B sfetch
+.I [options]
+.I seqname
+
+.SH DESCRIPTION
+
+.B sfetch
+retrieves the sequence named
+.I seqname
+from a sequence database.
+
+.PP
+Which database is used is controlled by the
+.B -d 
+and 
+.B -D
+options, or "little databases" and "big
+databases".
+The directory location of "big databases" can
+be specified by environment variables,
+such as $SWDIR for Swissprot, and $GBDIR
+for Genbank (see
+.B -D 
+for complete list). 
+A complete file path must be specified
+for "little databases".
+By default, if neither option is specified
+and the name looks like a Swissprot identifier
+(e.g. it has a _ character), the $SWDIR
+environment variable is used to attempt
+to retrieve the sequence 
+.I seqname
+from Swissprot.
+
+.PP
+A variety of other options are available which allow
+retrieval of subsequences
+.RI ( -f,-t );
+retrieval by accession number instead of
+by name 
+.RI ( -a );
+reformatting the extracted sequence into a variety
+of other formats
+.RI ( -F );
+etc.
+
+.PP
+If the database has been GSI indexed, sequence
+retrieval will be extremely efficient; else,
+retrieval may be painfully slow (the entire
+database may have to be read into memory to
+find 
+.IR seqname ).
+GSI indexing
+is recommended for all large or permanent 
+databases. 
+
+.pp
+This program was originally named 
+.B getseq,
+and was renamed because it clashed with a GCG
+program of the same name.
+
+.SH OPTIONS
+
+.TP
+.B -a 
+Interpret 
+.I seqname
+as an accession number, not an identifier.
+
+.TP 
+.BI -d " <seqfile>"
+Retrieve the sequence from a sequence file named
+.I <seqfile>.
+If a GSI index 
+.I <seqfile>.gsi
+exists, it is used to speed up the retrieval.
+
+.TP
+.BI -f " <from>"
+Extract a subsequence starting from position
+.I <from>,
+rather than from 1. See
+.B -t.
+If 
+.I <from> 
+is greater than
+.I <to>
+(as specified by the
+.B -t
+option), then the sequence is extracted as 
+its reverse complement (it is assumed to be
+nucleic acid sequence).
+
+.TP
+.B -h
+Print brief help; includes version number and summary of
+all options, including expert options.
+
+.TP
+.BI -o " <outfile>" 
+Direct the output to a file named
+.I <outfile>.
+By default, output would go to stdout. 
+
+.TP
+.BI -r " <newname>"
+Rename the sequence
+.I <newname>
+in the output after extraction. By default, the original
+sequence identifier would be retained. Useful, for instance,
+if retrieving a sequence fragment; the coordinates of
+the fragment might be added to the name (this is what Pfam
+does).
+
+.TP
+.BI -t " <to>"

+.SH NAME

+shuffle - randomize the sequences in a sequence file
+
+.SH SYNOPSIS
+.B shuffle
+.I [options]
+.I seqfile
+
+.SH DESCRIPTION
+
+.B shuffle
+reads a sequence file
+.I seqfile,
+randomizes each sequence, and prints the randomized sequences
+in FASTA format on standard output. The sequence names
+are unchanged; this allows you to track down the source
+of each randomized sequence if necessary.
+
+.pp
+The default is to simply shuffle each input sequence, preserving
+monosymbol composition exactly. To shuffle
+each sequence while preserving both its monosymbol and disymbol
+composition exactly, use the
+.I -d 
+option.
+
+.pp
+The
+.I -0
+and 
+.I -1
+options allow you to generate sequences with the same
+Markov properties as each input sequence. With
+.I -0,
+for each input sequence, 0th order Markov statistics
+are collected (e.g. symbol composition), and a new
+sequence is generated with the same composition.
+With 
+.I -1, 
+the generated sequence has the same 1st order 
+Markov properties as the input sequence (e.g.
+the same disymbol frequencies). 
+
+.pp
+Note that the default and
+.I -0,
+or 
+.I -d
+and 
+.I -1,
+are similar; the shuffling algorithms preserve
+composition exactly, while the Markov algorithms
+only expect to generate a sequence of similar
+composition on average.
+
+.pp
+Other shuffling algorithms are also available,
+as documented below in the options.
+
+.SH OPTIONS
+
+.TP
+.B -0
+Calculate 0th order Markov frequencies of each input sequence
+(e.g. residue composition); generate output sequence 
+using the same 0th order Markov frequencies.
+
+.TP
+.B -1
+Calculate 1st order Markov frequencies for each input
+sequence (e.g. diresidue composition); generate output
+sequence using the same 1st order Markov frequencies.
+The first residue of the output sequence is always
+the same as the first residue of the input sequence.
+
+.TP
+.B -d
+Shuffle the input sequence while preserving both
+monosymbol and disymbol composition exactly. Uses
+an algorithm published by  S.F. Altschul and B.W. Erickson,
+Mol. Biol. Evol. 2:526-538, 1985. 
+
+.TP
+.B -h
+Print brief help; includes version number and summary of
+all options, including expert options.
+
+.TP
+.B -l
+Look only at the length of each input sequence; generate
+an i.i.d. output protein sequence of that length,
+using monoresidue frequencies typical of proteins
+(taken from Swissprot 35).
+
+.TP
+.BI -n " <n>"
+Make 
+.I <n>
+different randomizations of each input sequence in
+.I seqfile, 
+rather than the default of one.
+
+.TP
+.B -r
+Generate the output sequence by reversing the
+input sequence. (Therefore only one "randomization"
+per input sequence is possible, so it's
+not worth using 
+.I -n
+if you use reversal.)
+
+.TP
+.BI -t " <n>"
+Truncate each input sequence to a fixed length of exactly
+.I <n>
+residues. If the input sequence is shorter than
+.I <n>
+it is discarded (therefore the output file may contain
+fewer sequences than the input file). 
+If the input sequence is longer than 
+.I <n>
+a contiguous subsequence is randomly chosen.
+
+.TP
+.BI -w " <n>"
+Regionally shuffle each input sequence in window sizes of
+.I <n>,
+preserving local residue composition in each window.
+Probably a better shuffling algorithm for biosequences
+with nonstationary residue composition (e.g. composition
+that is varying along the sequence, such as between
+different isochores in human genome sequence).
+
+.TP
+.B -B
+(Babelfish). Autodetect and read a sequence file format other than the
+default (FASTA). Almost any common sequence file format is recognized
+(including Genbank, EMBL, SWISS-PROT, PIR, and GCG unaligned sequence
+formats, and Stockholm, GCG MSF, and Clustal alignment formats). See
+the printed documentation for a complete list of supported formats.
+
+.SH EXPERT OPTIONS
+

+.SH NAME
+.TP 
+sreformat - convert sequence file to different format
+
+.SH SYNOPSIS
+.B sreformat
+.I [options]
+.I format
+.I seqfile
+
+.SH DESCRIPTION
+
+.B sreformat
+reads the sequence file
+.I seqfile
+in any supported format, reformats it
+into a new format specified by 
+.I format,
+then prints the reformatted text.
+
+.PP
+Supported input formats include (but are not limited to) the unaligned
+formats FASTA, Genbank, EMBL, SWISS-PROT, PIR, and GCG, and the
+aligned formats Stockholm, Clustal, GCG MSF, and Phylip.
+
+.PP
+Available unaligned output file format codes 
+include
+.I fasta
+(FASTA format);
+.I embl
+(EMBL/SWISSPROT format);
+.I genbank
+(Genbank format);
+.I gcg
+(GCG single sequence format);
+.I gcgdata
+(GCG flatfile database format);
+.I strider
+(MacStrider format);
+.I zuker
+(Zuker MFOLD format);
+.I ig
+(Intelligenetics format);
+.I pir
+(PIR/CODATA flatfile format);
+.I squid
+(an undocumented St. Louis format);
+.I raw
+(raw sequence, no other information).
+
+.pp
+The available aligned output file format
+codes include
+.I stockholm
+(PFAM/Stockholm format);
+.I msf
+(GCG MSF format); 
+.I a2m
+(aligned FASTA format, called A2M by the UC Santa Cruz
+HMM group);
+.I PHYLIP
+(Felsenstein's PHYLIP format); and
+.I selex
+(old SELEX/HMMER/Pfam annotated alignment format);
+
+.pp
+All thee codes are interpreted case-insensitively
+(e.g. MSF, Msf, or msf all work).
+
+.PP 
+Unaligned format files cannot be reformatted to
+aligned formats.
+However, aligned formats can be reformatted
+to unaligned formats -- gap characters are 
+simply stripped out.
+
+.PP
+This program was originally named
+.B reformat,
+but that name clashes with a GCG program of the same name.
+
+.SH OPTIONS
+
+.TP
+.B -a
+Enable alignment reformatting. By default, sreformat expects
+that the input file should be handled as an unaligned input
+file (even if it is an alignment), and it will not allow you
+to convert an unaligned file to an alignment (for obvious
+reasons).
+.pp
+This may seem silly; surely if sreformat can autodetect and parse
+alignment file formats as input, it can figure out when it's got an
+alignment! There are two reasons.  One is just the historical
+structure of the code. The other is that FASTA unaligned format and
+A2M aligned format (aligned FASTA) are impossible to tell apart with
+100% confidence.
+
+.TP
+.B -d 
+DNA; convert U's to T's, to make sure a nucleic acid
+sequence is shown as DNA not RNA. See
+.B -r.
+
+.TP
+.B -h
+Print brief help; includes version number and summary of
+all options, including expert options.
+
+.TP
+.B -l
+Lowercase; convert all sequence residues to lower case.
+See
+.B -u.
+
+.TP
+.B -r 
+RNA; convert T's to U's, to make sure a nucleic acid
+sequence is shown as RNA not DNA. See
+.B -d.
+
+.TP
+.B -u
+Uppercase; convert all sequence residues to upper case.
+See
+.B -l.
+
+.TP
+.B -x
+For DNA sequences, convert non-IUPAC characters (such as X's) to N's.
+This is for compatibility with benighted people who insist on using X
+instead of the IUPAC ambiguity character N. (X is for ambiguity
+in an amino acid residue). 
+.pp
+Warning: the code doesn't
+check that you are actually giving it DNA. It simply 
+literally just converts non-IUPAC DNA symbols to N. So 
+if you accidentally give it protein sequence, it will
+happily convert most every amino acid residue to an N.
+
+.TP
+.B -B
+(Babelfish). Autodetect and read a sequence file format other than the
+default (FASTA). Almost any common sequence file format is recognized
+(including Genbank, EMBL, SWISS-PROT, PIR, and GCG unaligned sequence
+formats, and Stockholm, GCG MSF, and Clustal alignment formats). See
+the printed documentation for a complete list of supported formats.
+
+
+.SH EXPERT OPTIONS
+
+.TP
+.BI --informat " <s>"
+Specify that the sequence file is in format 
+.I <s>,
+rather than the default FASTA format.
+Common examples include Genbank, EMBL, GCG, 
+PIR, Stockholm, Clustal, MSF, or PHYLIP; 
+see the printed documentation for a complete list
+of accepted format names.
+This option overrides the default format (FASTA)
+and the 
+.I -B
+Babelfish autodetection option.
+
+.TP
+.B --mingap
+If 
+.I seqfile
+is an alignment, remove any columns that contain 100% gap
+characters, minimizing the overall length of the alignment.
+(Often useful if you've extracted a subset of aligned
+sequences from a larger alignment.)
+
+.TP
+.B --pfam
+For SELEX alignment output format only, put the entire
+alignment in one block (don't wrap into multiple blocks).
+This is close to the format used internally by Pfam
+in Stockholm and Cambridge.
+
+.TP
+.B --sam
+Try to convert gap characters to UC Santa Cruz SAM style, where a .
+means a gap in an insert column, and a - means a
+deletion in a consensus/match column. This only
+works for converting aligned file formats, and only
+if the alignment already adheres to the SAM convention
+of upper case for residues in consensus/match columns,
+and lower case for residues in insert columns. This is
+true, for instance, of all alignments produced by old
+versions of HMMER. (HMMER2 produces alignments
+that adhere to SAM's conventions even in gap character choice.)
+This option was added to allow Pfam alignments to be
+reformatted into something more suitable for profile HMM
+construction using the UCSC SAM software.
+
+.TP
+.BI --samfrac " <x>"
+Try to convert the alignment gap characters and
+residue cases to UC Santa Cruz SAM style, where a .
+means a gap in an insert column and a - means a
+deletion in a consensus/match column, and 
+upper case means match/consensus residues and
+lower case means inserted resiudes. This will only
+work for converting aligned file formats, but unlike the
+.B --sam 
+option, it will work regardless of whether the file adheres
+to the upper/lower case residue convention. Instead, any 
+column containing more than a fraction 
+.I <x> 
+of gap characters is interpreted as an insert column,
+and all other columns are interpreted as match columns.
+This option was added to allow Pfam alignments to be
+reformatted into something more suitable for profile HMM
+construction using the UCSC SAM software.

+ *           the fraction of columns which are identically aligned.
+ * 
+ *           For all columns c in which either known1[c] or known2[c] 
+ *           is a non-gap, count an identity if those same symbols are
+ *           aligned somewhere in calc1/calc2. The score is identities/total
+ *           columns examined. (i.e. fully gapped columns don't count)
+ * 
+ *           more explicitly, identities come from:
+ *             both known and test aligned pairs have the same symbol in the first sequence aligned to
+ *               a gap in the second sequence;
+ *             both known and test aligned pairs have the same symbol in the second sequence
+ *               aligned to a gap in the first sequence;
+ *             the known alignment has symbols aligned at this column, and the test
+ *               alignment aligns the same two symbols.
+ * 
+ * Args:     known1, known2: trusted alignment of two sequences
+ *           calc1, calc2:   test alignment of two sequences

+ *           given a prior probability distribution for alignments.
+ *           I don't see how to describe such a distribution, let alone
+ *           sample it.
+ *           
+ *           This is a rough approximation that tries to capture some
+ *           desired properties. We assume the alignment is generated
+ *           by a simple HMM composed of match and insert states.
+ *           Given parameters (pop, pex) for the probability of opening
+ *           and extending an insertion, we can find the expected number
+ *           of match states, M, in the underlying model for each sequence.
+ *           We use an average M taken over all the sequences (this is
+ *           an approximation. The expectation of M given all the sequence
+ *           lengths is a nasty-looking summation.)
+ *

+ *           
+ *           Then, we assign positions in each raw sequence onto the M match
+ *           states and M+1 insert states of this "HMM", by rolling random
+ *           numbers and inserting the (rlen-M) inserted positions randomly
+ *           into the insert slots, taking into account the relative probability
+ *           of open vs. extend.
+ *           
+ *           The resulting alignment has two desired properties: insertions
+ *           tend to follow the HMM-like exponential distribution, and
+ *           the "sparseness" of the alignment is controllable through
+ *           pop and pex.

+ * Purpose:  Sometimes we've got to convert alignments to 
+ *           a lowest common denominator, and we need
+ *           a single specific gap character -- for example,
+ *           PSI-BLAST blastpgp -B takes a very simplistic
+ *           alignment input format which appears to only
+ *           allow '-' as a gap symbol.
+ *           
+ *           Anything matching the isgap() macro is
+ *           converted.
+ *
+ * Args:     aseq   - aligned character strings, [0..nseq-1][0..alen-1]
+ *           nseq   - number of aligned strings
+ *           alen   - length of alignment
+ *           gapsym - character to use for gaps.         
+ *
+ * Returns:  void ("never fails")

+ * NxN difference matrix (usually constructed by pairwise alignment 
+ * and similarity calculations for N sequences). Use the simple 
+ * cluster analysis part of the Fitch/Margoliash tree-building algorithm
+ * (as described by Fitch and Margoliash 1967 as well as Feng
+ * and Doolittle 1987) to calculate the topology of an "evolutionary
+ * tree" consistent with the difference matrix. Returns an array
+ * which represents the tree.
+ * 
+ * The input difference matrix is just an NxN matrix of floats.
+ * A good match is a small difference score (the algorithm is going
+ * to search for minima among the difference scores). The original difference
+ * matrix remains unchanged by the calculations.

+ * The output requires some explanation. A phylogenetic
+ * tree is a binary tree, with N "leaves" and N-1 "nodes". The
+ * topology of the tree may be completely described by N-1 structures
+ * containing two pointers; each pointer points to either a leaf
+ * or another node. Here, this is implemented with integer indices
+ * rather than pointers. An array of N-1 pairs of ints is returned.
+ * If the index is in the range (0..N-1), it is a "leaf" -- the
+ * number of one of the sequences. If the index is in the range
+ * (N..2N-2), it is another "node" -- (index-N) is the index
+ * of the node in the returned array.
+ * 
+ * If both indices of a member of the returned array point to
+ * nodes, the tree is "compound": composed of more than one
+ * cluster of related sequences.
+ * 
+ * The higher-numbered elements of the returned array were the
+ * first constructed, and hence represent the distal tips
+ * of the tree -- the most similar sequences. The root
+ * is node 0.
+ ******************************************************************
+ *
+ * Algorithm
+ * 
+ * INITIALIZATIONS:
+ *  - copy the difference matrix (otherwise the caller's copy would
+ *       get destroyed by the operations of this algorithm). If
+ *       it's asymmetric, make it symmetric.
+ *  - make a (0..N-1) array of ints to keep track of the indices in
+ *       the difference matrix as they get swapped around. Initialize
+ *       this matrix to 0..N-1.
+ *  - make a (0..N-2) array of int[2] to store the results (the tree
+ *       topology). Doesn't need to be initialized.
+ *  - keep track of a "N'", the current size of the difference
+ *       matrix being operated on.
+ *
+ * PROCESSING THE DIFFERENCE MATRIX:
+ *  - for N' = N down to N' = 2  (N-1 steps):
+ *    - in the half-diagonal N'xN' matrix, find the indices i,j at which
+ *      there's the minimum difference score
+ *      
+ *     Store the results:
+ *    - at position N'-2 of the result array, store coords[i] and 
+ *         coords[j].
+ *    
+ *     Move i,j rows, cols to the outside edges of the matrix:
+ *    - swap row i and row N'-2
+ *    - swap row j and row N'-1   
+ *    - swap column i and column N'-2
+ *    - swap column j and column N'-1
+ *    - swap indices i, N'-2 in the index array
+ *    - swap indices j, N'-1 in the index array
+ *    
+ *     Build a average difference score for differences to i,j:
+ *    - for all columns, find avg difference between rows i and j and store in row i: 
+ *       row[i][col] = (row[i][col] + row[j][col]) / 2.0
+ *    - copy the contents of row i to column i (it's a symmetric
+ *       matrix, no need to recalculate)
+ *    - store an index N'+N-2 at position N'-2 of the index array: means
+ *       that this row/column is now a node rather than a leaf, and
+ *       contains minimum values
+ *       
+ *     Continue:
+ *    - go to the next N'
+ *    
+ * GARBAGE COLLECTION & RETURN.

+ * 
+ * Usage: compalign <trusted-alignment> <test-alignment>
+ * 
+ * Calculate the fractional "identity" between the trusted alignment
+ * and the test alignment. The two files must contain exactly the same
+ * sequences, in exactly the same order.
+ * 
+ * The identity of the multiple sequence alignments is defined as
+ * the averaged identity over all N(N-1)/2 pairwise alignments. 
+ * 
+ * The fractional identity of two sets of pairwise alignments
+ * is in turn defined as follows (for aligned known sequences k1 and k2,
+ * and aligned test sequences t1 and t2):
+ * 
+ *           matched columns / total columns, 
+ *       
+ *       where total columns = the total number of columns in
+ *        which there is a valid (nongap) symbol in k1 or k2;
+ *        
+ *       matched columns = the number of columns in which one of the
+ *         following is true:
+ *         
+ *          k1 and k2 both have valid symbols at a given column; t1 and t2
+ *             have the same symbols aligned in a column of the t1/t2
+ *             alignment;
+ *             
+ *          k1 has a symbol aligned to a gap in k2; that symbol in t1
+ *             is also aligned to a gap;
+ *             
+ *          k2 has a symbol aligned to a gap in k1; that symbol in t2
+ *             is also aligned to a gap.
+ * 
+ * Because scores for all possible pairs are calculated, the
+ * algorithm is of order (N^2)L for N sequences of length L;
+ * large sequence sets will take a while.

+/* Function: ParsePAMFile()
+ * 
+ * Purpose:  Given a pointer to an open file containing a PAM matrix,
+ *           parse the file and allocate and fill a 2D array of
+ *           floats containing the matrix. The PAM file is
+ *           assumed to be in the format that NCBI distributes
+ *           with BLAST. BLOSUM matrices also work fine, as
+ *           produced by Henikoff's program "MATBLAS".
+ *          
+ *           Parses both old format and new format BLAST matrices.
+ *           Old format just had rows of integers.
+ *           New format includes a leading character on each row.
+ *
+ *           The PAM matrix is a 27x27 matrix, 0=A..25=Z,26=*.
+ *           Note that it's not a 20x20 matrix as you might expect;
+ *           this is for speed of indexing as well as the ability
+ *           to deal with ambiguous characters.
+ *           
+ * Args:     fp        - open PAM file
+ *           ret_pam   - RETURN: pam matrix, integers                   
+ *           ret_scale - RETURN: scale factor for converting
+ *                       to real Sij. For instance, PAM120 is
+ *                       given in units of ln(2)/2. This may
+ *                       be passed as NULL if the caller
+ *                       doesn't care.
+ * 
+ * Returns:  1 on success; 0 on failure and sets squid_errno to
+ *           indicate the cause. ret_pam is allocated here and
+ *           must be freed by the caller (use FreePAM).

+ * "generic key index" module: emulation of Perl hashes.
+ * Maps keys (ASCII char strings) to array index. Dynamically
+ * resizes the hash table. 
+ * 
+ * Limitations:
+ *     - hash table can only grow; no provision for deleting keys
+ *       or downsizing the hash table.
+ *     - Maximum hash table size set at 100003. Performance 
+ *       will degrade for key sets much larger than this.
+ *     - Assumes that integers are 32 bits (or greater). 
+ * 
+ * Defines a typedef'd structure:
+ *     gki           - a key index hash table.
+ * Provides functions:
+ *     GKIInit()     - start a hash table.
+ *     GKIStoreKey() - store a new key, get a unique index.                        
+ *     GKIKeyIndex() - retrieve an existing key's index.
+ *     GKIFree()     - free a hash table.
+ *     GKIStatus()   - Debugging: prints internal status of a hash struct
+ *            
+ *
+ * Note that there are no dependencies on squid; the gki.c/gki.h

+
+/* Function: Strparse()
+ * 
+ * Purpose:  Match a regexp to a string. Returns 1 if pattern matches,
+ *           else 0.
+ *
+ *           Much like Perl, Strparse() makes copies of the matching
+ *           substrings available via globals, sqd_parse[].
+ *           sqd_parse[0] contains a copy of the complete matched
+ *           text. sqd_parse[1-9] contain copies of up to nine
+ *           different substrings matched within parentheses.
+ *           The memory for these strings is internally managed and
+ *           volatile; the next call to Strparse() may destroy them.
+ *           If the caller needs the matched substrings to persist
+ *           beyond a new Strparse() call, it must make its own 
+ *           copies.
+ *           
+ *           A minor drawback of the memory management is that
+ *           there will be a small amount of unfree'd memory being
+ *           managed by Strparse() when a program exits; this may
+ *           confuse memory debugging (Purify, dbmalloc). The
+ *           general cleanup function SqdClean() is provided;
+ *           you can call this before exiting.
+ *           
+ *           Uses an extended POSIX regular expression interface.
+ *           A copylefted GNU implementation is included in the squid
+ *           implementation (gnuregex.c) for use on non-POSIX compliant
+ *           systems. POSIX 1003.2-compliant systems (all UNIX,
+ *           some WinNT, I believe) can omit the GNU code if necessary.
+ *           
+ *           I built this for ease of use, not speed nor efficiency.
+ *
+ * Example:  Strparse("foo-...-baz", "foo-bar-baz")  returns 0
+ *           Strparse("foo-(...)-baz", "foo-bar-baz")
+ *              returns 0; sqd_parse[0] is "foo-bar-baz";
+ *              sqd_parse[1] is "bar".
+ *              
+ * Args:     rexp  - regular expression, extended POSIX form
+ *           s     - string to match against
+ *           ntok  - number of () substrings we will save (maximum NSUBEXP-1)
+ *                   
+ * Return:   1 on match, 0 if no match

+ *                    msa = MSAAlloc(nseq, alen);
+ *                    
+ *           2) We know the number of sequences but not alen.

+ *                    msa = MSAAlloc(nseq, 0);
+ *              
+ *           3) We even don't know the number of sequences, so
+ *              we'll have to dynamically expand allocations.
+ *              We provide a blocksize for the allocation expansion,
+ *              and expand when needed.
+ *                    msa = MSAAlloc(10, 0);
+ *                    if (msa->nseq == msa->nseqalloc) MSAExpand(msa);   
+ *
+ * Args:     nseq - number of sequences, or nseq allocation blocksize
+ *           alen - length of alignment in columns, or 0      
+ *
+ * Returns:  pointer to new MSA object, w/ all values initialized.
+ *           Note that msa->nseq is initialized to 0, though space

+/* Function: ReadSELEX()
+ * Date:     SRE, Sun Jun  6 18:24:09 1999 [St. Louis]
+ *
+ * Purpose:  Parse an alignment read from an open SELEX format
+ *           alignment file. (SELEX is a single alignment format).
+ *           Return the alignment, or NULL if we've already read the
+ *           alignment or there's no alignment data in the file.
+ *           
+ * Limitations: SELEX is the only remaining multipass parser for
+ *           alignment files. It cannot read from gzip or from stdin.
+ *           It Die()'s here if you try. The reason for this
+ *           that SELEX allows space characters as gaps, so we don't
+ *           know the borders of an alignment block until we've seen
+ *           the whole block. I could rewrite to allow single-pass
+ *           parsing (by storing the whole block in memory) but
+ *           since SELEX is now legacy, why bother.
+ *           
+ *           Note that the interface is totally kludged: fastest
+ *           possible adaptation of old ReadSELEX() to the new
+ *           MSA interface.  
+ *
+ * Args:     afp  - open alignment file
+ *
+ * Returns:  MSA *  - an alignment object
+ *                    caller responsible for an MSAFree()
+ *           NULL if no alignment data.

+ *           Before the first call to sre_fgets(),

+ *           They're a linked pair, so don't muck with the

+ *
+ *           The reason to have it return a ptr to buf

+ *
+ * Purpose:  Dynamic memory version of strcat().
+ *           appends src to the string that dest points to,
+ *           extending allocation for dest if necessary.
+ *           
+ *           One timing experiment (100 successive appends of 
+ *           1-255 char) shows sre_strcat() has about a 20%
+ *           overhead relative to strcat(). However, if optional
+ *           length info is passed, sre_strcat() is about 30%
+ *           faster than strcat().
+ *           
+ * Args:     dest  - ptr to string (char **), '\0' terminated
+ *           ldest - length of dest, if known; or -1 if length unknown.
+ *           src   - string to append to dest, '\0' terminated       
+ *           lsrc  - length of src, if known; or -1 if length unknown.
+ *
+ *           dest may be NULL, in which case this is
+ *           the equivalent of dest = Strdup(src).
+ *           
+ *           src may also be NULL, in which case
+ *           dest is unmodified (but why would you want to pass
+ *           a NULL src?)
+ *           
+ *           if both dest and src are NULL, dest is
+ *           unmodified; it stays NULL.
+ * 
+ *           the length parameters are optional. If a -1
+ *           is passed, sre_strcat() will call strlen() to
+ *           determine the length itself. Passing length
+ *           info saves the strlen() calls and can speed things
+ *           up if lots of successive appends need to be done.
+ *           
+ * Returns:  new length of dest (>=0 on success);
+ *           dest is (probably) reallocated, and modified
+ *           to a longer string, '\0' terminated.

+ *
+ * Purpose:  Thread-safe version of strtok().
+ *
+ *           Returns ptr to next token in a string: skips

+ *            next delim character (or '\0') to set the end; replaces that
+ *            character with '\0'.
+ *           If there's still more string left, sets s to point to next 
+ *            character after the '\0' that was written, so successive 
+ *            calls extract tokens in succession. If there was no string
+ *            left, s points at the terminal '\0'.

+ *           *s can't be a constant string, since we write to it.

+ * SRE, Thu Aug  3 08:11:52 2000 [St. Louis] [moved to SQUID]
+ * 
+ * Reporting of cpu/system/elapsed time used by a process.
+ * thanks to Warren Gish for assistance.
+ * 
+ * Basic API:
+ * 
+ *   Stopwatch_t *w;
+ *   w = StopwatchCreate();
+ *   
+ *   StopwatchStart(w);
+ *   do_lots_of_stuff;
+ *   StopwatchStop(w);
+ *   StopwatchDisplay(stdout, "CPU time: ", w);
+ *   
+ *   StopwatchFree(w);
+ *   
+ * Some behavior can be controlled at compile time by #define's:
+ * 
+ *   SRE_STRICT_ANSI:  By default, stopwatch module assumes that a
+ *         machine is POSIX-compliant (e.g. has struct tms, sys/times.h, 
+ *         and times()). If compiled with -DSRE_STRICT_ANSI, reverts to 
+ *         pure ANSI C conformant implementation. This simpler system 
+ *         won't report system times, only user and elapsed times.
+ *         
+ *   SRE_ENABLE_PVM:   If compiled with -DSRE_ENABLE_PVM, the
+ *         functions StopwatchPVMPack() and StopwatchPVMUnpack()
+ *         are compiled, providing PVM communications ability.
+ *         
+ * One additional compile-time configuration note:        
+ *   PTHREAD_TIMES_HACK: Linux pthreads, as of RH6.0/glibc-devel-2.1.1-6, 
+ *         appears to interact poorly with times() -- usage times in all 
+ *         but the master thread are lost. A workaround for this bug is 
+ *         to run stopwatches in each worker thread, and accumulate those 
+ *         times back into the master stopwatch using StopwatchInclude().
+ *         (Just like a PVM implementation has to do.) In HMMER, this 
+ *         behavior is compiled in with -DPTHREAD_TIMES_HACK. No
+ *         changes are made in stopwatch functions themselves, though;
+ *         all the extra code is HMMER code. See hmmcalibrate.c for
+ *         an example.
+ * 
+ * See hmmcalibrate.c for examples of more complex usage
+ * in dealing with pthreads and PVM.

+ * Date:     SRE, Fri Jul 16 17:47:22 1999 [St. Louis]
+ *
+ * Purpose:  Implementation of Henikoff and Henikoff position-based
+ *           weights (JMB 243:574-578, 1994) [Henikoff94b].
+ *           
+ *           A significant advantage of this approach that Steve and Jorja
+ *           don't point out is that it is O(N) in memory, unlike
+ *           many other approaches like GSC weights or Voronoi.
+ *           
+ *           A potential disadvantage that they don't point out
+ *           is that in the theoretical limit of infinite sequences
+ *           in the alignment, weights go flat: eventually every
+ *           column has at least one representative of each of 20 aa (or 4 nt)
+ *           in it.
+ *           
+ *           They also don't give a rule for how to handle gaps.
+ *           The rule used here seems the obvious and sensible one
+ *           (ignore them). This means that longer sequences
+ *           initially get more weight; hence a "double
+ *           normalization" in which the weights are first divided
+ *           by sequence length (to compensate for that effect),
+ *           then normalized to sum to nseq.
+ *           
+ * Limitations:
+ *           Implemented in a way that's alphabet-independent:
+ *           it uses the 26 upper case letters as "residues".
+ *           Any alphabetic character in aseq is interpreted as
+ *           a unique "residue" (case insensitively; lower case
+ *           mapped to upper case). All other characters are
+ *           interpreted as gaps.
+ *           
+ *           This way, we don't have to pass around any alphabet
+ *           type info (DNA vs. RNA vs. protein) and don't have
+ *           to deal with remapping IUPAC degenerate codes
+ *           probabilistically. However, on the down side,
+ *           a sequence with a lot of degenerate IUPAC characters
+ *           will get an artifactually high PB weight.
+ *           
+ * Args:     aseq   - sequence alignment to weight

+/* Function: SingleLinkCluster()
+ * Date:     SRE, Fri Jul 16 15:02:57 1999 [St. Louis]
+ *
+ * Purpose:  Perform simple single link clustering of seqs in a
+ *           sequence alignment. A pairwise identity threshold
+ *           defines whether two sequences are linked or not.
+ *           
+ *           Important: runs in O(N) memory, unlike standard
+ *           graph decomposition algorithms that use O(N^2)
+ *           adjacency matrices or adjacency lists. Requires
+ *           O(N^2) time in worst case (which is when you have
+ *           no links at all), O(NlogN) in "average"
+ *           case, and O(N) in best case (when there is just
+ *           one cluster in a completely connected graph.
+ *           
+ *           (Developed because hmmbuild could no longer deal
+ *           with GP120, a 16,013 sequence alignment.)
+ *           
+ * Limitations: 
+ *           CASE-SENSITIVE. Assumes aseq have been put into
+ *           either all lower or all upper case; or at least,
+ *           within a column, there's no mixed case.
+ *           
+ * Algorithm: 
+ *           I don't know if this algorithm is published. I 
+ *           haven't seen it in graph theory books, but that might
+ *           be because it's so obvious that nobody's bothered.
+ *           
+ *           In brief, we're going to do a breadth-first search
+ *           of the graph, and we're going to calculate links
+ *           on the fly rather than precalculating them into
+ *           some sort of standard adjacency structure.
+ *           
+ *           While working, we keep two stacks of maximum length N:
+ *                a : list of vertices that are still unconnected.
+ *                b : list of vertices that we've connected to 
+ *                    in our current breadth level, but we haven't
+ *                    yet tested for other connections to a.
+ *           The current length (number of elements in) a and b are
+ *           kept in na, nb.
+ *                    
+ *           We store our results in an array of length N:
+ *                c : assigns each vertex to a component. for example
+ *                    c[4] = 1 means that vertex 4 is in component 1.
+ *                    nc is the number of components. Components
+ *                    are numbered from 0 to nc-1. We return c and nc
+ *                    to our caller.
+ *                    
+ *           The algorithm is:
+ *           
+ *           Initialisation: 
+ *                a  <-- all the vertices
+ *                na <-- N
+ *                b  <-- empty set
+ *                nb <-- 0
+ *                nc <-- 0
+ *                
+ *           Then:
+ *                while (a is not empty)
+ *                  pop a vertex off a, push onto b
+ *                  while (b is not empty)
+ *                    pop vertex v off b
+ *                    assign c[v] = nc
+ *                    for each vertex w in a:
+ *                       compare v,w. If w is linked to v, remove w
+ *                       from a, push onto b.

+/* Function: P7ViterbiAlignAlignment()
+ * Date:     SRE, Sat Jul  4 13:39:00 1998 [St. Louis]
+ *
+ * Purpose:  Align a multiple alignment to an HMM without
+ *           changing the multiple alignment itself.
+ *           Adapted from P7Viterbi().
+ *           
+ *           Heuristic; not a guaranteed optimal alignment.
+ *           Guaranteeing an optimal alignment appears difficult.
+ *           [cryptic note to myself:] In paths connecting to I* metastates,
+ *           recursion breaks down; if there is a gap in the
+ *           previous column for a given seq, we can't determine what state the
+ *           I* metastate corresponds to for this sequence, unless we
+ *           look back in the DP matrix. The lookback would either involve
+ *           recursing back to the previous M* metastate (giving a
+ *           O(MN^2) algorithm instead of O(MN)) or expanding the I*
+ *           metastate into 3^nseq separate I* metastates to keep track
+ *           of which of three states each seq is in. Since the second
+ *           option blows up exponentially w/ nseq, it is not attractive.
+ *           If the first option were used, the correct algorithm would be related to 
+ *           modelmakers.c:Maxmodelmaker(), but somewhat more difficult.
+ *           
+ *           The heuristic approach here is to calculate a "consensus"
+ *           sequence from the alignment, and align the consensus to the HMM.
+ *           Some hackery is employed, weighting transitions and emissions
+ *           to make things work (re: con and mocc arrays).
+ *
+ * Args:     aseq  - aligned sequences
+ *           ainfo - info for aseqs (includes alen, nseq, wgt)
+ *           hmm   - model to align to        
+ *
+ * Returns:  Traceback. Caller must free with P7FreeTrace().
+ *           pos[] contains alignment columns, indexed 1..alen.
+ *           statetype[] contains metastates M*, etc. as STM, etc.

+/* Function: PostprocessSignificantHit()
+ * Date:     SRE, Wed Dec 20 12:11:01 2000 [StL]
+ * 
+ * Purpose:  Add a significant hit to per-seq and per-domain hit
+ *           lists, after postprocessing the scores appropriately,
+ *           and making sure per-domain scores add up to the per-seq 
+ *           score.
+ *  
+ *          [doesn't really belong in core_algorithms.c, because
+ *           it's more of a hack than an algorithm, but on the other
+ *           hand it's now part of the core of how HMMER scores
+ *           things. Maybe there should be a core_hacks.c.]
+ *
+ *           Given: active hit lists for per-seq and per-domain
+ *           scores (e.g. hmmpfam and hmmsearch, collating their
+ *           results), and a new hit that's significant enough
+ *           that it may need to be reported in final output.
+ *           
+ *           Breaks the traceback into individual domain traces;
+ *           scores each one of them, then applies null2 correction
+ *           for biased composition. Recalculates the per-seq score
+ *           as the sum of the per-domain scores. Stores the hits
+ *           in the lists, for eventual sorting and output by the
+ *           caller.
+ * 
+ * Notes:    In principle we've got the score, and a pvalue, and a traceback
+ *           by doing the Viterbi algorithm, right? What else is left
+ *           to do? Well, in practice, life is more complicated, because
+ *           of the trace-dependent null2 score correction.
+ *           
+ *           After a null2 score correction is carried out on
+ *           each domain (the default) the number of detected domains
+ *           with scores > 0 may have decreased. We want the
+ *           global (per-seq) hit list to have the recalculated number of 
+ *           domains, not necessarily what Viterbi gave us. 
+ *           
+ *           Also, since we want the global score to be the sum of
+ *           the individual domains, but the null2 correction is
+ *           applied to each domain individually, we have to calculate
+ *           an adjusted global score. (To do otherwise invites
+ *           subtle inconsistencies; xref bug 2.)
+ *
+ *           We don't have final evalues, so we may put a few
+ *           more hits into the hit lists than we end up reporting.
+ *           The main output routine is responsible for final
+ *           enforcement of the thresholds.
+ *          
+ *           This routine is NOT THREADSAFE. When multithreaded,
+ *           with using shared ghit/dhit output buffers, calls to
+ *           PostprocessSignificantHit() need to be protected.
+ *           
+ * Args:     ghit     - an active list of per-seq (global) hits
+ *           dhit     - an active list of per-domain hits
+ *           tr       - the significant HMM/seq traceback we'll report on
+ *           hmm      - ptr to the HMM
+ *           dsq      - digitized sequence (1..L)
+ *           L        - length of dsq
+ *           seqname  - name of sequence (same as targname, in hmmsearch)
+ *           seqacc   - seq's accession (or NULL)
+ *           seqdesc  - seq's description (or NULL)
+ *           do_forward  - TRUE if we've already calculated final per-seq score
+ *           sc_override - per-seq score to use if do_forward is TRUE
+ *           do_null2    - TRUE to apply the null2 scoring correction
+ *           thresh      - contains the threshold/cutoff information.
+ *           hmmpfam_mode - TRUE if called by hmmpfam, else assumes hmmsearch;
+ *                          affects how the lists' sort keys are set.

+/* Function: WriteProfile()
+ * Date:     SRE, Wed Jan 21 07:58:09 1998 [St. Louis]
+ *
+ * Purpose:  Given an HMM, write a GCG profile .prf file as
+ *           output. Based on examination of Michael Gribskov's Fortran
+ *           source in GCG 9.1; on reverse engineering
+ *           by examination of GCG 9.1 output from "profilemake"
+ *           and how the .prf file is used by "profilesearch";
+ *           and on the GCG 9.0 documentation.
+ *           
+ *           See notes 28 Jan 98 for detail; in brief, the conversion goes like:
+ *           
+ *           PROF(i,k) = match score         =  msc(i,k) + TMM(k-1)
+ *           
+ *           GAP(k)    = cost per insertion  =  TMI(k-1) + TIM(k-1) - TMM(k-1) - TII(k-1)
+ *           LEN(k)    = cost per inserted x =  TII(k-1)
+ *           
+ *           QGAP(k)   = cost per deletion   =  TDM(k-1) + TMD(unknown) - TMM(k-1) - TDD(k-1)
+ *           QLEN(k)   = cost per deleted k  =  TDD(k-1)
+ *           
+ *           Note that GCG affine gaps are GAP + n * LEN;
+ *           HMMER affine gaps count (n-1) * gap-extend, thus an
+ *           extra TII gets taken away from GAP (and TDD from QGAP),
+ *           since GCG will charge it.
+ *           
+ *           Also note how the TMM transitions, which have no equivalent
+ *           in a profile, get smuggled in OK.
+ *           
+ *           Also note that GCG charges gaps using the profile position
+ *           /after/ the gap, not preceding the gap as HMMER does.
+ *           
+ *           Also note the TMD(unknown) in the QGAP calculation. HMMER
+ *           distinguishes between gap-open and gap-close, but GCG does not,
+ *           so there is a fundamental incompatibility here. Here
+ *           we use an upper (best-scoring, minimum-cost) bound. 
+ *           
+ *           And finally note that GCG's implementation forces GAP=QGAP and
+ *           LEN=QLEN. Here, we upper bound again. Compugen's implementation
+ *           allows an "extended profile" format which distinguishes between
+ *           the two. 
+ *           
+ *           The upper bound approach to these scores means that a 
+ *           score given by an emulated profile is an upper bound: the HMMER
+ *           score (for a single Smith/Waterman style local alignment)
+ *           cannot be better than this. This is intentional, so that
+ *           the Compugen BIC can be used for rapid prefiltering of
+ *           the database.
+ *           
+ *           To get a close approximation of hmmsw scores, call
+ *           profilesearch as
+ *                profilesearch -noave -nonor -gap 10 -len 1
+ *           On the Compugen BIC, using extended profiles, you want:
+ *                om -model=xsw.model -gapop=10 -gapext=1 -qgapop=10 -qgapext=1 -noave -nonor

+ *           nseq    - number of aseqs
+ *           eff_nseq- effective sequence number; weights normalize up to this.

+ * 
+ * Input/output of HMMs.
+ *
+ * As of HMMER 2.0, HMMs are saved by default in a tabular ASCII format
+ * as log-odds or log probabilities scaled to an integer. A binary save
+ * file format is also available which is faster to access (a
+ * consideration which might be important for HMM library applications).
+ * HMMs can be concatenated into HMM libraries.
+ * 
+ * A comment on loss of accuracy. Storing a number as a scaled log
+ * probability guarantees us an error of about 0.035% or
+ * less in the retrieved probability. We are relatively invulnerable
+ * to the truncation errors which HMMER 1.8 was vulnerable to.  
+ * 
+ * Magic numbers (both for the ASCII and binary save formats) are used 
+ * to label save files with a major version number. This simplifies the task of
+ * backwards compatibility as new versions of the program are created. 
+ * Reverse but not forward compatibility is guaranteed. I.e. HMMER 2.0
+ * can read `1.7' save files, but not vice versa. Note that the major
+ * version number in the save files is NOT the version of the software
+ * that generated it; rather, the number of the last major version in which
+ * save format changed.

+ *           based on sequence endpoints. M/I emissions are corrected;
+ *           C/N/J are not -- as if the nonmatching part and 
+ *           matching part were each generated by the best null model.
+ *           Each null model is constructed /post hoc/ from the
+ *           sequence composition of each matching domain (e.g.
+ *           a null2 model is constructed for each domain in a 
+ *           multihit trace).
+ *           
+ *           Constraints on the construction of this function include:
+ *            1) Paracel hardware can't deal with trace-dependent
+ *               null2 models. Original implementation of 
+ *               TraceScoreCorrection() was dependent on traceback
+ *               and could not be reproduced on GeneMatcher.
+ *               GeneMatcher may be able to deal w/ sequence endpoint
+ *               dependent rescoring, though.
+ *               Although this function looks like it's trace-
+ *               dependent (because it's being passed a p7trace_s
+ *               structure), it's really not; only the sequence
+ *               endpoints are being used.
+ *               
+ *            2) It is desirable that for multihit traces,
+ *               per-domain scores sum to the per-sequence score.
+ *               Otherwise people see this as a "bug" (cf. 
+ *               bug #2, David Kerk, NRC). HMMER calculates the
+ *               per-domain scores by going through a separate
+ *               TraceScore() call for each one and separately
+ *               correcting them with TraceScoreCorrection(),
+ *               so we have to do each domain in a full trace
+ *               by a similar mechanism -- even if this means that
+ *               we're adopting a very dubiously post hoc
+ *               null model.

+ * Purpose:  Given a sequence character x and an hmm emission probability
+ *           vector, calculate the log-odds (base 2) score of
+ *           the symbol.
+ *          
+ *           Easy if x is in the emission alphabet, but not so easy
+ *           is x is a degenerate symbol. The "correct" Bayesian
+ *           philosophy is to calculate score(X) by summing over
+ *           p(x) for all x in the degenerate symbol X to get P(X),
+ *           doing the same sum over the prior to get F(X), and
+ *           doing log_2 (P(X)/F(X)). This gives an X a zero score,
+ *           for instance.
+ *           
+ *           Though this is correct in a formal Bayesian sense --
+ *           we have no information on the sequence, so we can't
+ *           say if it's random or model, so it scores zero --
+ *           it sucks, big time, for scoring biological sequences.
+ *           Sequences with lots of X's score near zero, while
+ *           real sequences have average scores that are negative --
+ *           so the X-laden sequences appear to be lifted out
+ *           of the noise of a full histogram of a database search.
+ *           Correct or not, this is highly undesirable.
+ *           
+ *           So therefore we calculated the expected score of
+ *           the degenerate symbol by summing over all x in X:
+ *                 e_x log_2 (p(x)/f(x))
+ *           where the expectation of x, e_x, is calculated from
+ *           the random model.

+ *               to compile code for a quadprocessor, for instance.

+ *           of sequences into a new multiple alignment. 
+ *           
+ *           Insertions are put into lower case and 
+ *           are not aligned; instead, Nterm is right-justified,
+ *           Cterm is left-justified, and internal insertions
+ *           are split in half and the halves are justified in
+ *           each direction (the objective being to increase
+ *           the chances of getting insertions aligned well enough
+ *           for them to become a match). SAM gap char conventions
+ *           are used: - in match columns, . in insert columns
+ * 
+ * NOTE:     Does not recognize J state.
+ *
+ * Args:     dsq        - digitized unaligned sequences 
+ *           sqinfo     - array of info about the sequences
+ *           wgt        - weights on seqs
+ *           nseq       - number of sequences
+ *           mlen       - length of model (number of match states)
+ *           tr         - array of tracebacks
+ *           matchonly  - TRUE if we don't print insert-generated symbols at all

+Shiva: HMMER testsuite
+
+#####################################################################
+I. Compiled test drivers.
+---------------------------------------------------------------------
+
+- A test driver runs with no arguments, gives no output, 
+  and returns EXIT_SUCCESS if the test passes.
+- If the test fails, the test driver calls Die() to print a diagnostic on
+  stderr, and exit with EXIT_FAILURE.
+- The -v option always activates rudimentary verbose output on stdout.
+
+
+Current tests:
+---------------
+
+alignalign_test
+	Exercises P7ViterbiAlignAlignment() -- alignment of a fixed
+	multiple alignment to an HMM. Aligns fn3 seed alignment to
+	fn3 model, compares to results of aligning sequences individually;
+	if an excessive number of discrepancies are detected, test
+	fails.
+	Other files: fn3.seed, fn3.hmm.
+
+evd_test    
+	Exercises code in histogram.c, especially EVD fitting
+	Default generates 1000 EVD samples; fits EVD; tests that fitted
+        parameters are reasonably close to real ones. 
+
+masks_test  
+	Exercises code in masks.c 
+	Default runs XNU on a sequence and compares to a known result.
+
+parsingviterbi_test
+	Exercises P7ParsingViterbi() in core_algorithms.c
+	Runs Fn3 model against titin using both standard Viterbi and
+	ParsingViterbi; compares results for identity.
+
+tophits_test
+	Exercises tophits.c
+	Generates random scores in three tiers (good, middling, bad).
+	Uses RegisterHit() API; FullSort's them; tests that they
+	end up in the right number/order.
+
+trace_test
+	Exercises traceback code in core_algorithms.c
+	Runs a simple HMM against synthetic sequences designed to
+	exercise all possible arrangements of transitions, and
+	does a TraceVerify() to be sure resulting trace is internally
+	consistent. 
+
+viterbi_exercise
+	Exercises P7Viterbi and P7SmallViterbi in core_algorithms.c
+	Configures Fn3 model into various modes; generates 100 random
+ 	seqs from each configuration; does P7Viterbi and P7SmallViterbi
+	alignments, TraceVerify()'s them, checks them for identity.
+
+weeviterbi_test
+	Exercises P7WeeViterbi in core_algorithms.c
+	Runs RRM model against two subsequences of human U1A;
+	compares Viterbi trace to WeeViterbi trace.
+	
+#####################################################################
+II. Scripted test drivers.
+---------------------------------------------------------------------
+
+Optiontests.pl
+	Runs every documented option for every program, to be
+	sure they're really connected up.

+/* alignalign_test.c
+ * Sun Jul  5 13:42:41 1998
+ * 
+ * Test driver for P7ViterbiAlignAlignment().
+ * 
+ * The test is to 
+ *    1) read an alignment and a corresponding HMM
+ *    2) align the alignment to the HMM to get a master trace
+ *    3) map the alignment to the HMM to get another master trace
+ *    4) Test that the two master traces are identical; if not, fail.
+ *         This doesn't have to be true always, but it's true for the
+ *         fn3 test example.
+ *    5) Get imposed traces for each sequence
+ *    6) Viterbi align individual seqs to the model;
+ *           compare the imposed trace with the Viterbi trace;
+ *    7) If an excessive number of individual traces differ from
+ *          those imposed by master, fail.

+RIO - Phylogenomic Protein Function Analysis
+----------------------------------------------------------------
+
+
+RIO contains modified versions of programs written by others:
+
+1. TREE-PUZZLE
+   (Strimmer, K., and A. von Haeseler. 1996. Quartet puzzling: A quartet maximum
+    likelihood method for reconstructing tree topologies. Mol. Biol. Evol. 13: 964-969.) 
+   
+
+2. PHYLIP
+   (Felsenstein, J. 1993. PHYLIP (Phylogeny Inference Package) version 3.5c.
+    Distributed by the author.
+    Department of Genetics, University of Washington, Seattle.)
+
+
+Please note:
+------------
+
+1.  RIO uses modifications of these programs, the original versions were
+    written by others:
+
+    TREE-PUZZLE: Heiko A. Schmidt, Korbinian Strimmer, Martin Vingron, Arndt von Haeseler 
+
+    PHYLIP: Joseph Felsenstein, see also http://evolution.genetics.washington.edu/phylip/credits.html
+
+
+2.  The programs in the RIO distribution have been modified specifically
+    to work within RIO and cannot be used for any other purpose.
+
+
+3.  I am responsible for any accidentally introduced errors.
+
+
+4.  The original can be downloaded from the following sites:
+    TREE-PUZZLE: http://www.tree-puzzle.de/
+    PHYLIP: http://evolution.genetics.washington.edu/phylip.html
+
+
+RIO also contains hmmer (version 2.2g).

+# Generic Linux/Unix Makefile for PHYLIP 3.6.
+#
+# You should not need to change anything, though if you want you could
+# change the first (noncomment) statement to some directory location
+# that might be more useful.
+# The compressed tar archive phylip.tar.Z when uncompressed and extracted
+# puts the source code into a directory ./src, and also makes two other
+# directories ./exe and ./doc for the final executables and the documentation
+# files.  Only change the EXEDIR settings if you want something different
+# from that structure.
+# If it causes trouble in compiling, the CFLAGS statement below may also need
+# to be changed.
+#
+#  To use the PHYLIP v3.6 Makefile, type

+#                           in the current directory (where the source code is).
+#                           You will have to move the executable in to the
+#                           executables directory (e.g. "mv dnaml ../exe")
+#                           Note that the program name should be lower case.
+# 
+# ----------------------------------------------------------------------------
+#  (Starting here is the section where you may want to change things)
+# ----------------------------------------------------------------------------
+#
+# these are the statements we have been talking about:
+# one of the reasons for changing them would be to put the executables
+# on a different file system.
+# The default configuration is to have within the overall PHYLIP
+# directory three subdirectories:  "src" for source code, "exe" for the
+# executables, and "doc" for the documentation files.
+#
+# the following specifies the directory where the executables will be placed
+EXEDIR  = ../exe
+#
+# ----------------------------------------------------------------------------
+#
+# In the following statements (the ones that set CFLAGS, DFLAGS, LIBS
+# and DLIBS, CC and DC) you should make sure each is set properly.
+# Usually this will simply involve making sure that the proper statement
+# has no "#" as its first character and that all other possibilities
+# have "#" for their first character.
+#
+# ----------------------------------------------------------------------------
+#
+# This is the CFLAGS statement:
+#
+# if these statements say "-g"  and that causes trouble, remove the "-g"
+# if the "-lX11" does not work (X compiling not working), you may want to
+# remove that switch or fix it.
+#
+# Here are some possible CFLAGS statements:
+#
+#
+#A minimal one
+#CFLAGS =
+#
+# A basic one for debugging
+#CFLAGS  = -g 
+#
+# An optimized one for gcc
+CFLAGS  = -O3 -fomit-frame-pointer
+#
+# For some serious debugging using Gnu gcc
+#
+#CFLAGS=-g -Wall -Wmain -Wmissing-prototypes -Wreturn-type -Wstrict-prototypes  -Wunused -Werror -Wredundant-decls -Waggregate-return -Wcast-align -Wcomment
+#
+# For Digital Alpha systems with Compaq Tru64 Unix
+# (however, be aware that this may cause floating-point problems in programs
+#  like Dnaml owing to not using IEEE floating point standards).
+#CFLAGS = -fast
+#
+# ----------------------------------------------------------------------------
+#
+# and here are some possible DFLAGS statements:
+#
+# A minimal one
+#DFLAGS  = -DX $(CFLAGS)
+#
+# A basic one for debugging
+#DFLAGS  = -g -DX
+#
+#
+# For Gnu C++ for runs
+#DFLAGS  = -I/usr/X11R6/include -O3 -DX -fomit-frame-pointer
+#
+# For Digital Alpha systems with Compaq Tru64 Unix
+#DFLAGS = -DX -fast 
+#
+# for Linux with X Windows development packages installed
+# or for MacOS X with X Windows installed
+DFLAGS = $(CFLAGS) -DX -I/usr/X11R6/include
+#
+# ----------------------------------------------------------------------------
+#
+# These are the libraries for the CC and DC compiles, respectively
+#
+LIBS    = -lm
+#
+# if the Xlib library for the X windowing system is somewhere
+# unexpected, you may have to change the path /usr/X11R6/lib in this one
+#
+# For gcc for Linux with X windows development packages installed
+# or for MacOS X with X windows installed
+DLIBS= -L/usr/X11R6/lib/ -lX11 -lXaw -lXt
+#
+# ----------------------------------------------------------------------------
+#
+# The next two assignments are the invocations of the compiler for the
+# ordinary compiles and the tree-drawing programs, CC and DC
+#
+# This one specifies the "cc" C compiler
+CC        = cc $(CFLAGS)
+#
+#  To use GCC instead, if it is not the compiler that "cc" invokes
+#CC        = gcc $(CFLAGS)
+#
+# This one specifies the "cc" C compiler for the Draw programs
+DC        = cc $(DFLAGS)
+#
+# To use GCC instead, if it is not the compiler that "cc" invokes
+#DC        = gcc $(DFLAGS)

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+			  unique.
+
+4.1.a23   08.11.1999	- output of sequential and parallel version to *.pstep
+			  made identical
+
+4.1.a22   05.11.1999	- two different puzzle step tree outputs intruduced
+			  and added to the menu ("[ 1. 35 ](...);":
+			  - ordered unique tree list -> *.ptorder 
+			    Format: "[ 1. 35 ]"  (Ordernumber, Amount)
+			  - chronological tree list  -> *.pstep
+			    Format: "[ 1. 35 ]"  (Chunknumber, Amount in chunk)
+			  (the last is a problem in parallel, because the come
+			  in chunks, as scheduled)
+			- debugged the output
+4.1.a21   04.11.1999	- Makefile adjustments for other Plattforms
+			- pstep tree output changed. unique treestructures
+			  printed to *.pstep file with a leading comment
+			  containing an order number and the ammount padded
+			  with blanks (e.g. "[ 1. 356 ]('mouse'...").
+			  output is done right before writing the puzzle file.
+			- controlled MPI finish to the Quit menu option added
+
+4.1.a20   03.11.1999	- some garbage collection (free) added
+			- makefile adjusted, OFLAGS for optimization added
+			  (ppuzzle/MPICH has problems with -O, so the
+			  ppuzzle is created without optimization)
+			  Some minor changes in the makefiles
+			- still to do: garbage collection from 'internalnode'
+			  in master process
+
+4.1.a19   13.10.1999	- adding the output of standardized (i.e. sorted) 
+			  puzzling step trees. Those are printed to the 
+			  standard output at the moment. (Routines to sort 
+			  and print the trees implemented)
+	  14.10.1999	- routines for printing the sorted trees to a string.
+			  needed to send them between Master and Worker, and
+			  to have a unique key to sort and count the trees.
+          21.10.1999	- counting of sorted trees implemented by doubly linked
+			  list, sort routine, print to stdout
+          25.10.1999	- change place of writing distances to file right after 
+			  distances have been computed.
+			- output of puzzling step trees now with true name, 
+			  not numbers
+          02.11.1999	- parallel counting and sending of puzzling step trees
+			- some parallel sending bugs fixed
+
+4.1.a18   14.09.1999	- adding possibility to specify input file at 
+			  command line, this specifies also the output
+			  filenames (puzzle output: *.puzzle; treefile:
+			  *.tree; distances: *.dist; Triangel EPS: *.eps;
+			  unresolved: *.qlist; puzzling step trees: *.pstep)
+			  If an unexisting name is given, one has to reenter
+			  the right name, but the wrong one is used as prefix.
+          15.09.1999	- sending back of bad quartets from slaves added
+			- bug in quart2num fixed (not used before; was shifted

+			- changed all printf to FPRINTF(STDOUTFILE to
+			  change easily from stdout to a file.
+
+4.1.a15   08.07.1999	- scheduler for both parallel parts
+			- several small changes
+
+4.1.a14   25.06.1999	- computation of tree parallel, scheduler dependent,
+			  sending all biparts in one message instead of one
+			  by one 
+			- several small changes since a13 in sched.c, et al.
+
+4.1.a13   10.06.1999	- computation of tree parallel (chunk = #trees/#slaves)
+			- scheduling schemes implemented for minimum chunk sizes
+
+4.1.a12   07.06.1999	- computation of quartets properly parallel
+			- scheduling implemented
+			- counting of quartets by slave ajusted
+			- TODO: sending of bad quartets (array + list)
+			- distinction between '1st user tree' and 'NJ tree'
+			  in result output removed again
+
+4.1.a11   28.05.1999	- PP_SendDoQuartBlock, PP_RecvDoQuartBlock,
+			  PP_SendQuartBlock, PP_RecvQuartBlock

+
+4.1.a10   20.05.1999	- num2quart, numquarts, quart2num introduced
+			- parallel init/finalize, quartets computed on

+			  parameter exported
+
+4.1.a9    19.05.1999	- 'dvector forg' removed from onepamratematrix
+			  cmdline, because it's not used in the function.
+
+4.1.a8    18.05.1999	- add _GAMMA_ (not necessary) to gamma.h and _PUZZLE_
+			  to puzzle.h to avoid dublicate includes, possible
+			  due to ppuzzle.h
+			- ppuzzle added to makefile and to check
+			- 1st parallel version but no slave computations
+			  only sending parameters and done signals.
+
+4.1.a7    18.05.1999	- export reevaluation of tree and evaluation of
+			  usertrees to evaluatetree.
+
+4.1.a6    17.05.1999	- -DNEWFORLOOP added to fixed.src, because the changed
+			  for loop structure changes the sequence of randomized

+			- change 'int main()' to 'int main(argc, argv)'
+			- export more functionalities from main:
+			  memcleanup(), inputandinit(&argc, &argv)
+			- grouping if's (excluding eachother) together in 
+			  switch() 
+			- split treereavaluation and 1st usertree, 
+			  evaluate all usertrees together (TODO: both,

+			- MAKE CHECK added to ./makefile
+
+4.1.a5    16.05.1999	- adding ´dvector Brnlength´ to lslength cmdline to 
+			  reduce globality of Brnlength. (Later better to *Tree)
+
+4.1.a4    11.05.1999	- structure of for loops changed in computeallquartets
+			  and recon_tree, so that the quarted addresses are in 
+			  one contigous sequence (for a<b<c<d). This reduces 
+			  swapping on low memory machines and is easier to 
+			  parallelize.
+
+4.1.a3    07.05.1999	- export likelihood mapping from main to map_lklhd()
+			- export tree reconstuction from main to recon_tree()
+
+4.1.a2    06.05.1999	- moving all quartet_(a)lklhd calls to a general

+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory.  After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+/* general remarks:
+
+	for a quartet with the taxa a, b, c, d there are
+	three possible binary trees:
+	
+		1)  (a,b)-(c,d)
+		2)  (a,c)-(b,d)
+		3)  (a,d)-(b,c)
+	
+	For every quartet information about its branching structure is
+	stored. With the functions  readquartet  and  writequartet
+	this information can be accessed. For every quartet (a,b,c,d)
+	with a < b < c < d (taxa) the branching information is encoded
+	using 4 bits:
+	
+	value          8             4             2             1
+	        +-------------+-------------+-------------+-------------+
+	        |  not used   |   tree 3    |   tree 2    |   tree 1    |
+	        +-------------+-------------+-------------+-------------+
+
+	If the branching structure of the taxa corresponds to one of the
+	three trees the corresponding bit is set. If the branching structure
+	is unclear because two of the three trees have the same maximum
+	likelihood value the corresponding two bits are set. If the branching
+	structure is completely unknown all the bits are set (the highest
+	bit is always cleared because it is not used).

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.

+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of

+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free

+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes

+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or

+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of

+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it

+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program

+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+VERSION CHANGE
+==============
+
+4.1.a26   25.11.1999	- Makefile made universal for pauzzle and ppuzzle
+			- lines not needed removed from puzzle.h
+
+4.1.a25   19.11.1999	- Output file prefixes for distances, trees, and 
+			  puzzlereport changed in user trees analysis case 
+			  to user tree file name
+			- Temporary output of likelihood to treefile added
+
+4.1.a24   11.11.1999	- Output of puzzling step trees changed
+			  ptorder: [ orderno # % ID #UniqTopos #Steps ]PHYLIP
+			  pstep:   chunk #InChunk sum ID #UniqTopos #Steps
+			- preliminary leap frog RNG implemented, i.e. uses
+			  the rand4 in the usual way in the sequential case.
+			  If run in parallel all rand4 are initialized with
+			  the same seed and started with PP_Myid-th random
+			  number. after that each process uses the every
+			  PP_NumProcs-th random number to make sure that these
+			  unique.
+
+4.1.a23   08.11.1999	- output of sequential and parallel version to *.pstep
+			  made identical
+
+4.1.a22   05.11.1999	- two different puzzle step tree outputs intruduced
+			  and added to the menu ("[ 1. 35 ](...);":
+			  - ordered unique tree list -> *.ptorder 
+			    Format: "[ 1. 35 ]"  (Ordernumber, Amount)
+			  - chronological tree list  -> *.pstep
+			    Format: "[ 1. 35 ]"  (Chunknumber, Amount in chunk)
+			  (the last is a problem in parallel, because the come
+			  in chunks, as scheduled)
+			- debugged the output
+4.1.a21   04.11.1999	- Makefile adjustments for other Plattforms
+			- pstep tree output changed. unique treestructures
+			  printed to *.pstep file with a leading comment
+			  containing an order number and the ammount padded
+			  with blanks (e.g. "[ 1. 356 ]('mouse'...").
+			  output is done right before writing the puzzle file.
+			- controlled MPI finish to the Quit menu option added
+
+4.1.a20   03.11.1999	- some garbage collection (free) added
+			- makefile adjusted, OFLAGS for optimization added
+			  (ppuzzle/MPICH has problems with -O, so the
+			  ppuzzle is created without optimization)
+			  Some minor changes in the makefiles
+			- still to do: garbage collection from 'internalnode'
+			  in master process
+
+4.1.a19   13.10.1999	- adding the output of standardized (i.e. sorted) 
+			  puzzling step trees. Those are printed to the 
+			  standard output at the moment. (Routines to sort 
+			  and print the trees implemented)
+	  14.10.1999	- routines for printing the sorted trees to a string.
+			  needed to send them between Master and Worker, and
+			  to have a unique key to sort and count the trees.
+          21.10.1999	- counting of sorted trees implemented by doubly linked
+			  list, sort routine, print to stdout
+          25.10.1999	- change place of writing distances to file right after 
+			  distances have been computed.
+			- output of puzzling step trees now with true name, 
+			  not numbers
+          02.11.1999	- parallel counting and sending of puzzling step trees
+			- some parallel sending bugs fixed
+
+4.1.a18   14.09.1999	- adding possibility to specify input file at 
+			  command line, this specifies also the output
+			  filenames (puzzle output: *.puzzle; treefile:
+			  *.tree; distances: *.dist; Triangel EPS: *.eps;
+			  unresolved: *.qlist; puzzling step trees: *.pstep)
+			  If an unexisting name is given, one has to reenter
+			  the right name, but the wrong one is used as prefix.
+          15.09.1999	- sending back of bad quartets from slaves added
+			- bug in quart2num fixed (not used before; was shifted 
+			  by 1)
+			- first version of a README added ;-)
+
+4.1.a17   03.08.1999	- Recv-Error in receiving DoPuzzleBlock fixed
+			- double freeing of same MPI_Datatype fixed
+			- changing of scheduling algorithm to smaller chunks 
+			  in gss -> sgss
+          13.09.1999	- bug fixed in optimization routine in ml2.c:
+			  boundary check added
+
+4.1.a16   12.07.1999	- slight changes in verbosity levels
+			- changed all printf to FPRINTF(STDOUTFILE to
+			  change easily from stdout to a file.
+
+4.1.a15   08.07.1999	- scheduler for both parallel parts
+			- several small changes
+
+4.1.a14   25.06.1999	- computation of tree parallel, scheduler dependent,
+			  sending all biparts in one message instead of one
+			  by one 
+			- several small changes since a13 in sched.c, et al.
+
+4.1.a13   10.06.1999	- computation of tree parallel (chunk = #trees/#slaves)
+			- scheduling schemes implemented for minimum chunk sizes
+
+4.1.a12   07.06.1999	- computation of quartets properly parallel
+			- scheduling implemented
+			- counting of quartets by slave ajusted
+			- TODO: sending of bad quartets (array + list)
+			- distinction between '1st user tree' and 'NJ tree'
+			  in result output removed again
+
+4.1.a11   28.05.1999	- PP_SendDoQuartBlock, PP_RecvDoQuartBlock,
+			  PP_SendQuartBlock, PP_RecvQuartBlock
+			- mallocquartets() changed from global to local
+			  variables to be more flexible
+			- Quartet computation moved to slave (badquartet
+			  handling missing: output, badquartet vector);
+			- distinction between '1st user tree' and 'NJ tree'
+			  added in result output (puzzle1.c around l.1756)
+
+4.1.a10   20.05.1999	- num2quart, numquarts, quart2num introduced
+			- parallel init/finalize, quartets computed on
+			  master and slave, compared -> equal -> all necessary
+			  parameter exported
+
+4.1.a9    19.05.1999	- 'dvector forg' removed from onepamratematrix
+			  cmdline, because it's not used in the function.
+
+4.1.a8    18.05.1999	- add _GAMMA_ (not necessary) to gamma.h and _PUZZLE_
+			  to puzzle.h to avoid dublicate includes, possible
+			  due to ppuzzle.h
+			- ppuzzle added to makefile and to check
+			- 1st parallel version but no slave computations
+			  only sending parameters and done signals.
+
+4.1.a7    18.05.1999	- export reevaluation of tree and evaluation of
+			  usertrees to evaluatetree.
+
+4.1.a6    17.05.1999	- -DNEWFORLOOP added to fixed.src, because the changed
+			  for loop structure changes the sequence of randomized 
+			  quartets during likelihood mapping
+			- change 'int main()' to 'int main(argc, argv)'
+			- export more functionalities from main:
+			  memcleanup(), inputandinit(&argc, &argv)
+			- grouping if's (excluding eachother) together in 
+			  switch() 
+			- split treereavaluation and 1st usertree, 
+			  evaluate all usertrees together (TODO: both,
+			  treereavaluation and usertrees in one loop)
+			- MAKE CHECK added to ./makefile
+
+4.1.a5    16.05.1999	- adding ´dvector Brnlength´ to lslength cmdline to 
+			  reduce globality of Brnlength. (Later better to *Tree)
+
+4.1.a4    11.05.1999	- structure of for loops changed in computeallquartets
+			  and recon_tree, so that the quarted addresses are in 
+			  one contigous sequence (for a<b<c<d). This reduces 
+			  swapping on low memory machines and is easier to 
+			  parallelize.
+
+4.1.a3    07.05.1999	- export likelihood mapping from main to map_lklhd()
+			- export tree reconstuction from main to recon_tree()
+
+4.1.a2    06.05.1999	- moving all quartet_(a)lklhd calls to a general 
+			  purpose routine compute_quartlklhds()
+
+4.1.a1   06.05.1999	- Macro constants for typ_optn and puzzlemode
+			  for better readability.
+			- Ring counter for typ_optn and puzzlemode in
+			  the menu realized with mod (%) instead of IF.
+			- Possibility added to switch to a fixed random 
+			  seed (-1) or/and fixed 'random' integers (0)
+			  by using -DFIXEDRANDSEED and -DFIXEDINTRAND options.

+/* general remarks:
+
+	for a quartet with the taxa a, b, c, d there are
+	three possible binary trees:
+	
+		1)  (a,b)-(c,d)
+		2)  (a,c)-(b,d)
+		3)  (a,d)-(b,c)
+	
+	For every quartet information about its branching structure is
+	stored. With the functions  readquartet  and  writequartet
+	this information can be accessed. For every quartet (a,b,c,d)
+	with a < b < c < d (taxa) the branching information is encoded
+	using 4 bits:
+	
+	value          8             4             2             1
+	        +-------------+-------------+-------------+-------------+
+	        |  not used   |   tree 3    |   tree 2    |   tree 1    |
+	        +-------------+-------------+-------------+-------------+
+
+	If the branching structure of the taxa corresponds to one of the
+	three trees the corresponding bit is set. If the branching structure
+	is unclear because two of the three trees have the same maximum
+	likelihood value the corresponding two bits are set. If the branching
+	structure is completely unknown all the bits are set (the highest
+	bit is always cleared because it is not used).

+Overview of the Perl scripts in this directory
+----------------------------------------------
+
+This directory contains a collection of (mostly horrible)
+Perl scripts. Some of them are still maintained, such as 
+phylo_pl.pl. 
+
+Some of the scripts in this directory relay heavily
+on forester.pm.
+
+
+
+RIO pipeline:
+- rio.pl
+- makeTree.pl
+- p7extract.pl
+- multifetch.pl
+
+
+Running a parallelized RIO web server:
+- nph-riowebserver
+- rio_slave.pl
+- rio_slave_driver.pl
+- queue.pm
+
+
+To prepare data to be used by RIO:
+- bootstrap_cz.pl
+- pfam2slx.pl
+- extractSWISS-PROT.pl
+- extractTrembl.pl
+- pfam2pwd.pl
+
+
+To run multiple RIO analyses in an automated fashion:
+- Xrio.pl
+
+
+To analyze RIO results (of Xrio.pl runs):
+- bootstrapCounter.pl
+- bootstrapSelector.pl
+- diffFinder3.pl
+
+
+Counting of species in SWISS-PROT and TrEMBL:
+- countSpeciesSPTrEMBL.pl

+# Purpose:
+# Bootstrap resamples an alignment in PHYLIP sequential format <bootstraps>
+# times.
+# Amino acid sequences must only be represented by uppercase letters (A-Z)
+# and '-'.
+# In mode 0 it saves the positions which it used to create the
+# bootstrapped alignment into <positions outfile>.
+# Mode 1 allows to recreate exactly the same boostrapped alignment
+# by reading in a <positions infile>.
+# Sequence names are normalized to $LENGTH_OF_NAME characters.
+# The output alignment is in PHYLIP's sequential or interleaved format.
+# (These two are the same in this case, since all the seqs will be one
+# line in length (no returns in seq).)
+# 
+# Usage:
+# bootstrap_cz.pl <mode (0 or 1)> <bootstraps> <alignment infile> 
+# <alignment outfile> <positions out- (mode 0) or in-file (mode 1)>
+# [random number seed (mode 0 only)]

+# Purpose. Extracts AC, DE, and OS from a "trembl.dat" file.
+#          The output is used by "rio.pl".
+#          If a species list (format: SWISS-PROT-code=full name) is supplied:
+#          only sequences from species found in this list are written to
+#          outfile and their full species names replaced with their SWISS-PROT
+#          code (recommended).
+#
+# Usage.   extractTrembl.pl <infile> <outfile> [species list] 
+
+# Remark.  Need to re-run this if species in species tree or species list
+#          are added/changed or if a new version of Pfam is used!!
+
+# Some "heuristic" is required for Synechococcus, Synechocystis, Anabaena:

+#  Requirements  makeTree is part of the RIO/FORESTER suite of programs.
+#  ------------  Many of its global variables are set via rio_module.pm.
+#
+#
+#  Note. Use xt.pl (for Pfam alignments) or mt.pl (for other alignments)
+#  to run makeTree.pl on whole directories of alignments files.       
+#
+#
+#
+#  Usage
+#  -----
+#
+#  Tree calculation based on a Pfam/Clustal W alignment
+#  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#
+#     makeTree.pl [-options] <input alignment in SELEX (Pfam), PHYLIP
+#     sequential format, or Clustal W output> <outputfile>
+#     [path/name for temporary directory to be created]
+#
+#     Example:
+#     "% makeTree.pl -UTB1000S41NDXV /DB/PFAM/Full/IL5 IL5_tree"
+#
+#
+#  Tree calculation based on precalculated pairwise distances
+#  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#  Consensus tree will have no branch length values.
+#  Precalculated pairwise distances are the output of "pfam2pwd.pl",
+#  number of bootstraps needs to match the one used for the pwds.
+#
+#     makeTree.pl <-options, includes "F"> <pwdfile: boostrapped pairwise
+#     distances> <outputfile> [path/name for temporary directory
+#     to be created]
+#
+#     Example:
+#     "% makeTree.pl -FB100S21XV /pfam2pwd_out/IL5.pwd IL5_tree"
+#
+#
+#  Tree calculation based on precalculated pairwise distances
+#  and matching alignment
+#  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#  Consensus tree will have branch length values.
+#  Precalculated pairwise distances and the matching (processed)
+#  alignment are the output of "pfam2pwd.pl", number of bootstraps
+#  needs to match the one used for the pwds, matrix needs to match
+#  the one used for the pwds.
+#
+#     makeTree.pl <-options, includes "UF"> <pwdfile: boostrapped pairwise
+#     distances> <alnfile: corresponding alignment>
+#     <outputfile> [path/name for temporary directory to be created]
+#         
+#     Example:
+#     "% makeTree.pl -UFLB100S21XV /pfam2pwd_out/IL5.pwd /pfam2pwd_out/IL5.aln IL5_tree"
+#
+#
+#  Options
+#  -------
+#
+#  N  : Suggestion to remove columns in the alignment which contain gaps.
+#       Gaps are not removed, if, after removal of gaps, the resulting alignment would
+#       be shorter than $MIN_NUMBER_OF_AA. Default is not to remove gaps.
+#  Bx : Number of bootstrapps. B0: do not bootstrap. Default is 100 bootstrapps.
+#       The number of bootstrapps should be divisible by 10.
+#  U  : Use TREE-PUZZLE to calculate ML branchlengths for consesus tree, in case of 
+#       bootstrapped analysis.
+#  J  : Use JTT matrix (Jones et al. 1992) in TREE-PUZZLE, default: PAM.
+#  L  : Use BLOSUM 62 matrix (Henikoff-Henikoff 92) in TREE-PUZZLE, default: PAM.
+#  M  : Use mtREV24 matrix (Adachi-Hasegawa 1996) inTREE-PUZZLE, default: PAM.
+#  W  : Use WAG matrix (Whelan-Goldman 2000) in TREE-PUZZLE, default: PAM.
+#  T  : Use VT matrix (Mueller-Vingron 2000) in TREE-PUZZLE, default: PAM.
+#  P  : Let TREE-PUZZLE choose which matrix to use, default: PAM.
+#  E  : Exact parameter estimates in TREE-PUZZLE, default: Approximate.
+#       Model of rate heterogeneity in TREE-PUZZLE (default: Uniform rate)
+#  g  : 8 Gamma distributed rates
+#  t  : Two rates (1 invariable + 1 variable)
+#  m  : Mixed (1 invariable + 8 Gamma rates)
+#  R  : Randomize input order in PHYLIP NEIGHBOR.
+#  A  : Use PHYLIP PROTPARS instead of NEIGHBOR (and no pairwise distance calculation).
+#  jx : Number of jumbles when using PHYLIP PROTPARS (random seed set with Sx).
+#  Sx : Seed for random number generator(s). Must be 4n+1. Default is 9.
+#  X  : To keep multiple tree file (=trees from bootstrap resampled alignments).
+#  D  : To keep (and create in case of bootstrap analysis) pairwise distance matrix file.
+#       This is created form the not resampled (original) alignment.
+#  C  : Calculate pairwise distances only (no tree). Bootstrap is always 1.
+#       No other files are generated.  
+#  F  : Pairwise distance (pwd) file as input (instead of alignment).
+#       No -D, -C, and -N options available in this case.
+#  V  : Verbose.
+#  #  : Only for rio.pl: Do not calculate consensus tree ("I" option in rio.pl).
+#
+#
+#
+# History:
+# -------
+#
+# 09/06/03: Added "#" option (to be used only for rio.pl).
+# 03/24/04: Do not replace "?" with "-" in method pfam2phylip.

+
+  Requirements  makeTree is part of the RIO/FORESTER suite of programs.
+  ------------  Many of its global variables are set via rio_module.pm.
+
+
+
+  Note. Use xt.pl (for Pfam alignments) or mt.pl (for other alignments) 
+  to run makeTree.pl on whole directories of alignments files. 
+
+
+
+  Usage
+  -----
+
+  Tree calculation based on a Pfam/Clustal W alignment
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+      makeTree.pl [-options] <input alignment in SELEX (Pfam), PHYLIP
+      sequential format, or Clustal W output> <outputfile>
+      [path/name for temporary directory to be created]
+
+     Example:
+     "% makeTree.pl -UTB1000S41NDXV /DB/PFAM/Full/IL5 IL5_tree"
+
+
+  Tree calculation based on precalculated pairwise distances
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Consensus tree will have no branch length values.
+  Precalculated pairwise distances are the output of "pfam2pwd.pl",
+  number of bootstraps needs to match the one used for the pwds.
+
+     makeTree.pl <-options, includes "F"> <pwdfile: boostrapped pairwise
+     distances> <outputfile> [path/name for temporary directory
+     to be created]
+
+     Example:
+     "% makeTree.pl -FB100S21XV /pfam2pwd_out/IL5.pwd IL5_tree"
+
+
+  Tree calculation based on precalculated pairwise distances
+  and matching alignment
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Consensus tree will have branch length values.
+  Precalculated pairwise distances and the matching (processed)
+  alignment are the output of "pfam2pwd.pl", number of bootstraps
+  needs to match the one used for the pwds, matrix needs to match
+  the one used for the pwds.
+
+     makeTree.pl <-options, includes "UF"> <pwdfile: boostrapped pairwise
+     distances> <alnfile: corresponding alignment>
+     <outputfile> [path/name for temporary directory to be created]
+         
+     Example:
+     "% makeTree.pl -UFLB100S21XV /pfam2pwd_out/IL5.pwd /pfam2pwd_out/IL5.aln IL5_tree"
+
+
+  Options
+  -------
+
+  N  : Suggestion to remove columns in the alignment which contain gaps.
+       Gaps are not removed, if, after removal of gaps, the resulting alignment would
+       be shorter than $MIN_NUMBER_OF_AA. Default is not to remove gaps.
+  Bx : Number of bootstrapps. B0: do not bootstrap. Default is 100 bootstrapps.
+       The number of bootstrapps should be divisible by 10.
+  U  : Use TREE-PUZZLE to calculate ML branchlengths for consesus tree, in case of 
+       bootstrapped analysis.
+  J  : Use JTT matrix (Jones et al. 1992) in TREE-PUZZLE, default: PAM.
+  L  : Use BLOSUM 62 matrix (Henikoff-Henikoff 92) in TREE-PUZZLE, default: PAM.
+  M  : Use mtREV24 matrix (Adachi-Hasegawa 1996) inTREE-PUZZLE, default: PAM.
+  W  : Use WAG matrix (Whelan-Goldman 2000) in TREE-PUZZLE, default: PAM.
+  T  : Use VT matrix (Mueller-Vingron 2000) in TREE-PUZZLE, default: PAM.
+  P  : Let TREE-PUZZLE choose which matrix to use, default: PAM.
+  E  : Exact parameter estimates in TREE-PUZZLE, default: Approximate.
+       Model of rate heterogeneity in TREE-PUZZLE (default: Uniform rate)
+  g  : 8 Gamma distributed rates
+  t  : Two rates (1 invariable + 1 variable)
+  m  : Mixed (1 invariable + 8 Gamma rates)
+  R  : Randomize input order in PHYLIP NEIGHBOR.
+  A  : Use PHYLIP PROTPARS instead of NEIGHBOR (and no pairwise distance calculation).
+  jx : Number of jumbles when using PHYLIP PROTPARS (random seed set with Sx).
+  Sx : Seed for random number generator(s). Must be 4n+1. Default is 9.
+  X  : To keep multiple tree file (=trees from bootstrap resampled alignments).
+  D  : To keep (and create in case of bootstrap analysis) pairwise distance matrix file.
+       This is created form the not resampled (original) alignment.
+  C  : Calculate pairwise distances only (no tree). Bootstrap is always 1.
+       No other files are generated.  
+  F  : Pairwise distance (pwd) file as input (instead of alignment).
+       No -D, -C, and -N options available in this case.
+  V  : Verbose.
+  #  : Only for rio.pl: Do not calculate consensus tree ("I" option in rio.pl).
+

+
+  Requirements  phylo_pl is part of the FORESTER collection of programs.
+  ------------  Many of its global variables are set via forester.pm.
+
+  Note. Use xt.pl (for Pfam alignments) or mt.pl (for other alignments) 
+  to run phylo_pl.pl on whole directories of alignments files. 
+
+  Usage
+  -----
+
+      phylo_pl.pl [-options] <input alignment in SELEX (Pfam), PHYLIP
+      sequential format, or Clustal W output> <outputfile>
+      [path/name for temporary directory to be created]
+
+     Example:
+     "% phylo_pl.pl -B100q\@1nbS9X IL5.aln IL5_tree"
+
+  Options
+  -------
+ 
+  Bx : Number of bootstraps. B0: do not bootstrap. Default is 100 bootstrapps.
+       The number of bootstrapps should be divisible by 10.
+  J  : Use JTT matrix (Jones et al. 1992) in TREE-PUZZLE and/or PHYML, RAXML, default: VT (Mueller-Vingron 2000).
+  L  : Use BLOSUM 62 matrix (Henikoff-Henikoff 92) in TREE-PUZZLE and/or PHYML, RAXML, default: VT.
+  M  : Use mtREV24 matrix (Adachi-Hasegawa 1996) in TREE-PUZZLE and/or PHYML, default: VT.
+  W  : Use WAG matrix (Whelan-Goldman 2000) in TREE-PUZZLE and/or PHYML, RAXML, default: VT.
+  P  : Use PAM matrix (Dayhoff et al. 1978) in TREE-PUZZLE and/or PHYML, RAXML, default: VT.
+  D  : Use DCMut matrix (Kosial and Goldman, 2005) in PHYML, RAXML, VT in TREE-PUZZLE.
+  A  : Let TREE-PUZZLE choose which matrix to use, default: VT
+  E  : Exact parameter estimates in TREE-PUZZLE, default: Approximate.
+       Model of rate heterogeneity in TREE-PUZZLE (default: Uniform rate):
+  g  : 8 Gamma distributed rates
+  t  : Two rates (1 invariable + 1 variable)
+  m  : Mixed (1 invariable + 8 Gamma rates)
+  q\@x: Use FastME, x: 1: GME
+                      2: BME
+                      3: NJ

+  rx : Number of relative substitution rate categories in PHYML (default is 4).
+  jx : Number of jumbles (input order randomization) for PHYLIP FM, ME, PROTPARS, and PROML (default is 2) (random seed set with Sx).
+  I  : Estimate proportion of invariable sites in RAXML and/or PHYML (otherwise, proportion "0.0" is used in PHYML)
+  G  : to turn on global rearrangements in PHYLIP FM, ME, and PROML
+  Sx : Seed for random number generator(s). Must be 4n+1. Default is 9.
+  X  : To keep multiple tree file (=trees from bootstrap resampled alignments) and 
+       pairwise distance matrix file (in case of bootstrap analysis).

+# -----------------
+#
+# No "G=", "H=", "F=", "T=", "a=", "b=", "s", "f" in modes 1 and 2.
+#
+#
+# A=<String> Pfam alignment name (mandatory). This specifies the alignment
+#            against which the RIO analysis is to be performed.
+#            In modes 1 and 2: Pfam model (alignment) name
+#                              (e.g. "A=aconitase").
+#            In modes 3 and 4: Pfam alignment path/name
+#                              (e.g. "A=/path/to/your/pfam/Full/aconitase").
+#
+# Q=<String> Path/name of file containing the query sequence
+#            (in FASTA format or raw sequence) (mandatory in modes 1 and 3).
+#
+# N=<String> Query name (mandatory). This must include the SWISS-PROT code
+#            for the species of the query after a "_" (e.g. "N=QUERY_HAEIN").
+#            If the query sequence is already in the alignment (modes 2 and 4)
+#            the complete name needs to be specified -- including "/xxx-xxx".
+#
+# O=<String> Output file path/name (mandatory).
+#
+# T=<char>   Model for pairwaise distance calculation:
+#            J=JTT, B=BLOSUM 62, M=mtREV24, V=VT, W=WAG, P=PAM.
+#            BLOSUM 62 is default.
+#            (Not in modes 1 and 2; these modes use $MATRIX_FOR_PWD instead.)
+#
+#            In modes 1 and 3, a HMM is needed to align the query sequence to
+#            the alignment and either one of the following options must be
+#            employed:
+# H=<String> HMM name: This uses hmmfetch to retrieve a HMM from
+#            $PFAM_HMM_DB.
+# F=<String> HMM file: This directly reads the HMM from a file.
+#
+# S=<String> Species tree file path/name (in NHX format) (optional).
+#            If not specified, $SPECIES_TREE_FILE_DEFAULT is used.
+#
+# G=<String> Species names file (optional). Only sequences associated with
+#            species found in this file are used.
+#            In the species names file, individual species names must be
+#            separated by newlines and lines starting with "#" are ignored.    
+#            While only sequences associated with species found in the species
+#            tree ("S=") are used for the actual RIO analysis, this allows to 
+#            remove sequences prior to tree calculation (which is the most

+
+ It is highly recommended that you read this paper before
+ installing and/or using RIO. (Included in the RIO 
+ distribution as PDF: "RIO.pdf".)
+ 
+
+ Before rio.pl can be used, some variables in rio_module.pm need to be set, 
+ as described in RIO_INSTALL.
+
+
+
+ Usage: rio.pl <Mode: 1, 2, 3, or 4> <tagged arguments, single letter arguments>
+ -----
+
+
+ Examples:
+ ---------
+
+ % RIO1.1/perl/rio.pl 1 A=aconitase Q=RIO1.1/LEU2_HAEIN N=QUERY_HAEIN O=out1 p I C E
+ 
+ % RIO1.1/perl/rio.pl 2 A=aconitase N=LEU2_LACLA/5-449 O=out2 p I C E
+
+ % RIO1.1/perl/rio.pl 3 A=/path/to/my/pfam/Full/aconitase H=aconitase Q=RIO1.1/LEU2_HAEIN N=QUERY_HAEIN O=out3 p I C E
+
+ % RIO1.1/perl/rio.pl 4 A=/path/to/my/pfam/Full/aconitase N=LEU2_LACLA/5-449 O=out4 p I C E
+
+ % RIO1.1/perl/rio.pl 3 A=/path/to/my/pfam/Full/aconitase b=/path/to/my/pfam/Seed/aconitase Q=RIO1.1/LEU2_HAEIN N=QUERY_HAEIN O=out5 p I C E
+
+
+
+ Modes:
+ ------
+
+ 1: RIO analysis based on precalculated pairwise distances
+    alignment does not contain query sequence
+
+ 2: RIO analysis based on precalculated pairwise distances
+    alignment does contain query sequence
+
+ 3: RIO analysis based on Pfam alignments,
+    alignment does not contain query sequence
+
+ 4: RIO analysis based on Pfam alignments,
+    alignment does contain query sequence
+
+
+
+ Tagged arguments:
+ -----------------
+
+ No "G=", "H=", "F=", "T=", "a=", "b=", "s", "f" in modes 1 and 2.
+
+
+ A=<String> Pfam alignment name (mandatory). This specifies the alignment
+            against which the RIO analysis is to be performed.
+            In modes 1 and 2: Pfam model (alignment) name
+                              (e.g. "A=aconitase").
+            In modes 3 and 4: Pfam alignment path/name
+                              (e.g. "A=/path/to/your/pfam/Full/aconitase").
+
+ Q=<String> Path/name of file containing the query sequence
+            (in FASTA format or raw sequence) (mandatory in modes 1 and 3).
+
+ N=<String> Query name (mandatory). This must include the SWISS-PROT code
+            for the species of the query after a "_" (e.g. "N=QUERY_HAEIN").
+            If the query sequence is already in the alignment (modes 2 and 4)
+            the complete name needs to be specified -- including "/xxx-xxx".
+
+ O=<String> Output file path/name (mandatory).
+
+ T=<char>   Model for pairwaise distance calculation:
+            J=JTT, B=BLOSUM 62, M=mtREV24, V=VT, W=WAG, P=PAM.
+            BLOSUM 62 is default.
+            (Not in modes 1 and 2; these modes use \$MATRIX_FOR_PWD instead.)
+
+            In modes 1 and 3, a HMM is needed to align the query sequence to
+            the alignment and either one of the following options must be
+            employed:
+ H=<String> HMM name: This uses hmmfetch to retrieve a HMM from
+            \$PFAM_HMM_DB.
+ F=<String> HMM file: This directly reads the HMM from a file.
+
+ S=<String> Species tree file path/name (in NHX format) (optional).
+            If not specified, \$SPECIES_TREE_FILE_DEFAULT is used.
+
+ G=<String> Species names file (optional). Only sequences associated with
+            species found in this file are used.
+            In the species names file, individual species names must be
+            separated by newlines and lines starting with "#" are ignored.    
+            While only sequences associated with species found in the species
+            tree ("S=") are used for the actual RIO analysis, this allows to 
+            remove sequences prior to tree calculation (which is the most
+            time consuming step).  
+
+ P=<int>    Sort priority (default is 12):
+            0 : Ortholog  
+            1 : Ortholog,         Super ortholog
+            2 : Super ortholog,   Ortholog
+            3 : Ortholog,         Distance
+            4 : Distance,         Ortholog
+            5 : Ortholog,         Super ortholog,   Distance  
+            6 : Ortholog,         Distance,         Super ortholog
+            7 : Super ortholog,   Ortholog,         Distance
+            8 : Super ortholog,   Distance,         Ortholog
+            9 : Distance,         Ortholog,         Super ortholog
+           10 : Distance,         Super ortholog,   Ortholog
+           11 : Ortholog,         Subtree neighbor, Distance 
+           12 : Ortholog,         Subtree neighbor, Super ortholog,   Distance (default)
+           13 : Ortholog,         Super ortholog,   Subtree neighbor, Distance
+           14 : Subtree neighbor, Ortholog,         Super ortholog,   Distance
+           15 : Subtree neighbor, Distance,         Ortholog,         Super ortholog   
+           16 : Ortholog,         Distance,         Subtree neighbor, Super ortholog 
+           17 : Ortholog,         Subtree neighbor, Distance,         Super ortholog 
+
+ a=<int>    Bootstraps for tree construction (not in modes 1 and 2).
+            Default is 100.   
+
+ L=<int>    Threshold for orthologies for output. Default is 0.
+ v=<int>    Threshold for ultra-paralogies for output. Default is 50.
+
+ U=<int>    Threshold for orthologies for distance calculation. Default is 60.
+
+ X=<int>    In case of more than one putative orthologs:
+            number of sd the distance query - LCA has to differ
+            from the mean to generate a warning. Default is 2.
+
+ Y=<int>    In case of no putative orthologs:
+            number of sd the distance query - root has to differ
+            from mean to generate a warning. Default is 2.
+
+ Z=<double> In case of one putative ortholog:
+            threshold for factor between the two distances to their
+            LCA (larger/smaller) to generate a warning. Default is 2.
+
+ B=<int>    Threshold for subtree-neighborings. Default is 0.
+
+ b=<String> Build HMM from seed alignment with "hmmbuild -s" (optional).
+            This is to prevent from finding multiple domains per sequence
+            (i.e. prevents "cutting" the query sequence). Give path/name to
+            Seed with this.
+
+ j=<String> Name for temporary directory (optional).
+
+ y=<int>    Seed for random number generator. Default is 41.
+
+ I          Create and save a rooted, with duplication vs speciation,
+            and orthology information annotated gene tree.
+            If precalculated distances are used (modes 1 and 2): this gene
+            tree is a NJ tree calculated based on the non-bootstrap resampled
+            (original) pairwise distances.
+            If precalculated distances are not used (modes 3 and 4): this gene
+            is a consenus tree with ML branch length values and is also
+            annotated with bootstrap values for each node.
+
+            Options for output:
+ p          Output ultra-paralogs.
+ D          Description from SWISS-PROT and TrEMBL.
+ C          Complete description from SWISS-PROT and TrEMBL.
+ E          118 character output instead of 78 character output.
+
+ K          Keep intermediate files (they will go into the same directory 
+            as the output file, their names are the same as of the output
+            file, with various suffixes added).
+
+ s          Ignore non SWISS-PROT sequences (i.e. sequences from TrEMBL)
+            in the Pfam alignment.
+
+ f          Try to ignore TrEMBL "fragments" (sequences with "fragment" in
+            their description).
+
+ +          Parallel, use machines listed in file \$NODE_LIST.
+
+ x          RIO used as web server -- HTML output.
