5 hmmcalibrate - calibrate HMM search statistics
15 reads an HMM file from
17 scores a large number of synthesized random sequences with it, fits an
18 extreme value distribution (EVD) to the histogram of those scores, and
21 now including the EVD parameters.
25 may take several minutes (or longer) to run.
26 While it is running, a temporary file called
28 is generated in your working directory.
31 prematurely (ctrl-C, for instance), your original
33 will be untouched, and you should delete the
41 Print brief help; includes version number and summary of
42 all options, including expert options.
48 Sets the maximum number of CPUs that the program
49 will run on. The default is to use all CPUs
50 in the machine. Overrides the HMMER_NCPU
51 environment variable. Only affects threaded
52 versions of HMMER (the default on most systems).
56 Fix the length of the random sequences to
60 is a positive (and reasonably sized) integer.
61 The default is instead to generate sequences with
62 a variety of different lengths, controlled by a Gaussian
63 (normal) distribution.
67 Save a histogram of the scores and the fitted theoretical curve
73 Set the mean length of the synthetic sequences to
77 is a positive real number. The default is 350.
81 Set the number of synthetic sequences to
85 is a positive integer. If
86 .I <n> is less than about 1000, the fit to the EVD may fail.
89 will give better determined EVD parameters. The default
90 is 5000; it was empirically chosen as
91 a tradeoff between accuracy and computation time.
95 Run on a Parallel Virtual Machine (PVM). The PVM must
96 already be running. The client program
98 must be installed on all the PVM nodes.
99 Optional PVM support must have been compiled into
104 Set the standard deviation of the synthetic sequence
105 length distribution to
109 is a positive real number. The default is 350. Note that the
110 Gaussian is left-truncated so that no sequences have lengths
115 Set the random seed to
119 is a positive integer. The default is to use
121 to generate a different seed for each run, which
122 means that two different runs of
124 on the same HMM will give slightly different
126 this option to generate reproducible results for
129 runs on the same HMM.
