NAME
       cmpress - prepare a covariance model database for cmscan

SYNOPSIS
       cmpress [options] <cmfile>

DESCRIPTION
       Starting	 from  a CM database <cmfile> in standard Infernal-1.1 format,
       construct binary	compressed datafiles for cmscan.  The cmpress step  is
       required	for cmscan to work.

       The  <cmfile> must be have already been calibrated with cmcalibrate for
       cmpress to work.

       Four files are created: <cmfile>.i1m, <cmfile>.i1i,  <cmfile>.i1f,  and
       <cmfile>.i1p.   The  <cmfile>.i1m  file contains	the covariance models,
       associated filter p7 profile HMMs and their annotation in a binary for-
       mat.  The <cmfile>.i1i file is an SSI index for the <cmfile>.i1m	 file.
       The <cmfile>.i1f	file contains precomputed data structures for the fast
       heuristic  filter  (the	SSV  filter) for the filter p7 profile HMMs in
       <cmfile>.  The <cmfile>.i1p file	contains precomputed  data  structures
       for the rest of each profile filter p7 HMM.

       <cmfile>	 may  not  be  '-' (dash); running cmpress on a	standard input
       stream rather than a file is not	allowed.

OPTIONS
       -h     Help; print a brief reminder  of	command	 line  usage  and  all
	      available	options.

       -F     Force; overwrites	any previous cmpress'ed	datafiles. The default
	      is  to bitch about any existing files and	ask you	to delete them
	      first.
