EFETCH(1)
NAME
efetch - retrieve entries from sequence databases.
SYNOPSIS
efetch -options [database:]<query>
DESCRIPTION
In the late 90s efetch was a very popular tool to extremely quickly
retrieve entried from the most common public bioinformatics sequence
and motif databases. We will learn from the Debian and Ubuntu popularity contest effort if the package is possibly gaining a larger userbase
again.
DATABASES
SWissprot/SP, PIR, WOrmpep/WP, EMbl, GEnbank/GB, ProDom, ProSite
OPTIONS:
-a Search with Accession number
-f Fasta format output
-q Sequence only output (one line)
-s <#> Start at position #
-e <#> Stop at position #
-o More options and info...
-D <dir> Specify database directory
-H Display index header data
-p Display entrynames in search path
-r Print sequence in 'raw' format
-m Fetch from mixed mini database
-M Mini format output
- -b Do NOT reverse the order of bytes (SunOS, IRIX do reverse, Alpha
- not)
- -d <dbfile> Specify database file (avoid this)
- -i <idxfile> Specify index file (avoid this)
- -l <divfile> Specify division lookup table (avoid this)
- -B <database> Specify database (archaic)
- -A Only return entryname for accession number
- -n <name> Give the sequence this name
- -x Don't require query to match entry's name exactly (avoid)
- -w For Wormpep: also fetch cross-referenced SwissProt entry
- -h shows this help text
ENVIRONMENT
SWDIR = SwissProt directory - database and EMBL index files
PIRDIR = PIR -- " -- WORMDIR = Wormpep -- " -- EMBLDIR
= EMBL -- " -- GBDIR = Genbank -- " -- PRODOMDIR =
ProDom -- " -- PROSITEDIR = ProSite -- " -- DBDIR = User's
own -- " -- (fasta format)
- SEQDB database file (default SwissProt)
- SEQDBIDX index file DIVTABL division lookup table
- Ex. setenv DBDIR /pubseq/seqlibs/embl/
- Note that Prodom family consensus seqs can be fetched by PD:_#
