+ PROBCONS
+ ~~~~~~~~
+
+ Probabilistic consistency-based multiple sequence alignment
+
+-----------------------------------------------------------------
+
+PROBCONS is a novel tool for generating multiple alignments
+of protein sequences. Using a combination of probabilistic
+modeling and consistency-based alignment techniques, PROBCONS
+has achieved the highest accuracy of all alignment methods to
+date.
+
+PROBCONS was developed by Chuong B. Do in collaboration with
+Michael Brudno in the research group of Serafim Batzoglou,
+Department of Computer Science, Stanford University.

+Version History
+
+1.0, 3/23/2004 (Chuong Do)
+ -- initial release
+
+1.01, 3/25/2004 (Chuong Do)
+ -- fixed error in training procedure
+ -- retrained default parameters for 1 and 2 pairs of insert
+ states
+
+1.02, 4/17/2004 (Chuong Do)
+ -- replaced LOG_ADD and EXP routines
+ -- added support for reading MSF format files
+ -- added two extra utilities for scoring PROBCONS alignments
+ (for benchmarking purposes)
+ -- added the "compare" program for scoring alignments
+ according to a reference alignment with respect to
+ sum-of-pairs and column scores
+ -- added the "fixref" program for adjusting PREFAB
+ alignments to contain all letters of the input
+ sequences; basically the main program for PROBCONS
+ "hacked" to get the job done
+
+1.03, 5/3/2004 (Chuong Do)
+ -- added option to do all-pairs pairwise alignments instead
+ of constructing a full multiple alignment
+ -- added support for reading DIALIGN style files
+ -- enabled support for using BAliBASE annotations for scoring
+ BAliBASE alignments
+ -- several minor bug fixes thanks to Bob Edgar
+ -- added "project" program to project multiple alignment to
+ pairwise alignments
+
+1.04, 5/9/2004 (Chuong Do)
+ -- switched over to default of one-insert state pair
+ -- retrained default parameters
+ -- added annotation scores
+ -- small changes to model topology to make end gaps symmetrical
+ -- added makegnuplot utility to plot annotation scores
+
+1.05, 5/26/2004 (Chuong Do)
+ -- added cutoff filtering for posterior scores
+ -- made small corrections to recurrences for computing alignments
+ -- added CLUSTALW output support
+
+1.06, 7/13/2004 (Chuong Do)
+ -- ProbCons is now PUBLIC DOMAIN software.
+
+1.07, 8/30/2004 (Chuong Do)
+ -- Fixed CLUSTALW output for sequence names (thanks to John Calley
+ for pointing this out)
+
+1.08, 8/31/2004 (Chuong Do)
+ -- Added option for alignment order output (-a).
+
+1.09, 9/1/2004 (Chuong Do)
+ -- PROBCONS now allows input files with existing gaps -- these are
+ automatically stripped before alignment.
+
+1.10, 3/16/2005 (Chuong Do)
+ -- Reduced memory consumption by
+ -- not storing posterior matrix transposes
+ -- restricting consistency-derived posterior matrices to original posterior matrix
+
+1.11, 12/1/2006 (Chuong Do)
+ -- Fixed bug with conflict between --annot and -a options
+
+1.12, 4/1/2006 (Chuong Do)
+ -- Fixed GCC 4.3 compatibility problems (thanks to Martin Michlmayr and Charles Plessy)
