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.
