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.
