NAME

       hmmfetch - retrieve profile HMM(s) from a file

SYNOPSIS

       hmmfetch [options] <hmmfile> <key>
	(retrieves HMM named <key>)

       hmmfetch -f [options] <hmmfile> <keyfile>
	(retrieves all HMMs listed in <keyfile>)

       hmmfetch --index [options] <hmmfile>
	(indexes <hmmfile> for fetching)

DESCRIPTION

       Quickly retrieves one or more profile HMMs from an <hmmfile> (a large Pfam database, for example).

       The <hmmfile> must be indexed first, using hmmfetch --index.  The index is a binary file named <hmmfile>.ssi.

       The default mode is to retrieve a single profile by name or accession, called the <key>.  For example:

	 % hmmfetch Pfam-A.hmm Caudal_act
	 % hmmfetch Pfam-A.hmm PF00045

       With  the  -f option, a <keyfile> containing a list of one or more keys is read instead.  The first whitespace-delimited field on each non-
       blank non-comment line of the <keyfile> is used as a <key>, and any remaining data on the line is ignored; this allows a variety of  white-
       space  delimited  datafiles  to	be used as <keyfile>s.	The <keyfile> argument can be a '-' (dash) character, in which case the keyfile is
       read from standard input; this allows unix ninjas to construct sophisticated invocations using pipes.

       By default, the HMM is printed to standard output in HMMER3 format.

OPTIONS

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

       -f     The second commandline argument is a <keyfile> instead of a single <key>.  The first field on each line of the <keyfile> is used	as
	      a retrieval <key> (an HMM name or accession).  Blank lines and comment lines (that start with a # character) are ignored.

       -o <f> Output HMM(s) to file <f> instead of to standard output.

       -O     Output  HMM(s) to individual file(s) named <key> instead of standard output. With the -f option, this can result in many files being
	      created.

       --index
	      Instead of retrieving one or more profiles from <hmmfile>, index the <hmmfile> for future retrievals.  This creates a  <hmmfile>.ssi
	      binary index file.
