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 format.  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.
