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
