NAME

       srf_list - Lists and/or counts the contents of an SRF file

SYNOPSIS

       srf_list  [options] srf_archive ...

DESCRIPTION

       srf_list  lists  the filenames held within one or more SRF container.  To simply count the
       contents rather than list them specify the -c option. Note that when in count-only mode if
       an  index  is  present it will be used to determine the number of entries in the index and
       hence sequences in the SRF file. The index cannot  be  used  when  listing  the  filenames
       however as the index itself does not contain the full filenames.

       Note that it is not possible to count sequences matching certain patterns or with specific
       flags set. srf_info is a more general purpose tool that may cover this.

OPTIONS

       -c     Counts sequences instead of listing them.  Note  that  this  may  be  substantially
              faster than listing if an index exists.

       -v     Verbose  mode.  This  gives summary count information per file rather than just the
              total at the end.

       -l     Long format. When listing sequence names this  also  provides  information  on  the
              position  in  the  archive and the size of the sequence specific data block and the
              size of the shared data block header.

EXAMPLES

       To count the total number of sequences in several SRF files:

           srf_list -c *.srf

       To produce a "fofn" (file of filenames) for an SRF file:

           srf_list foo.srf > foo.fofn
