NAME

       afetch - retrieve an alignment from an alignment database

SYNOPSIS

       afetch [options] alignmentdb key

       afetch --index alignmentdb

DESCRIPTION

       afetch retrieves the alignment named key from an alignment database in file alignmentdb.

       alignmentdb  is  a  "multiple  multiple  alignment"  file  in Stockholm (e.g. native Pfam)
       format.

       key is either the name (ID) of the alignment, or its accession number (AC).

       The alignmentdb file should first  be  SSI  indexed  with  afetch  --index  for  efficient
       retrieval.  An  SSI  index  is  not  required,  but alignment retrieval without one may be
       painfully slow.

OPTIONS

       -h     Print brief help; includes version number and summary  of  all  options,  including
              expert options.

EXPERT OPTIONS

       --index
              Instead  of  retrieving  a  key,  the  special  command  afetch --index alignmentdb
              produces an SSI index of the names and accessions of the  alignments  in  the  file
              alignmentdb.  This should be run once on the alignmentdb file to prepare it for all
              future afetch's.
