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
