fastacmd - retrieve FASTA sequences from a BLAST database
fastacmd [-] [-D N] [-I] [-L start,stop] [-P N] [-S N] [-T] [-a] [-c]
[-d str] [-i str] [-l N] [-o filename] [-p type] [-s str] [-t]
fastacmd retrieves FASTA formatted sequences from a blast(1) database
formatted using the ‘-o’ option. An example fastacmd call would be
fastacmd -d nr -s p38398
A summary of options is included below.
- Print usage message
-D N Dump the entire database in some format:
2 GI list
3 Accession.version list
-I Print database information only (overrides all other options)
Range of sequence to extract (0 in start is beginning of
sequence, 0 in stop is end of sequence, default is whole
-P N Retrieve sequences with Protein Identification Group (PIG) N.
-S N Strand on subsequence (nucleotide only):
1 top (default)
-T Print taxonomic information for requested sequence(s)
-a Retrieve duplicate accessions
-c Use ^A (\001) as non-redundant defline separator
-d str Database (default is nr)
-i str Input file with GIs/accessions/loci for batch retrieval
-l N Line length for sequence (default = 80)
Output file (default = stdout)
Type of file:
G guess (default): look for protein, then nucleotide
-s str Comma-delimited search string(s). GIs, accessions, loci, or
fullSeq-id strings may be used, e.g., 555, AC147927,
-t Definition line should contain target GI only
0 Completed successfully.
1 An error (other than those below) occurred.
2 The BLAST database was not found.
3 A search (accession, GI, or taxonomy info) failed.
4 No taxonomy database was found.
