Biopiece: hmmer_seq

Description

hmmer_seq uses HMMER to search for protein motifs in peptide sequeces in the stream using a specified database of motif models.

The resulting records look like this:

REC_TYPE: HMMER
S_ID: test
S_AC: -
Q_ID: HORMA
Q_AC: PF02301.13
E_VAL_SEQ: 5.8e-27
SCORE_SEQ: 80.9
BIAS_SEQ: 3.6
E_VAL_DOM: 7.4e-27
SCORE_DOM: 80.5
BIAS_DOM: 2.5
EXP: 1.1
REG: 1
CLU: 0
OV: 0
ENV: 1
DOM: 1
REP: 1
INC: 1
DESC: -
---

HMMER v. 3.0 or later must be installed for hmmer_seq to work. Read more about HMMER here:

Usage

... | hmmer_seq [options] -d <index>

Options

[-?         | --help]                 #  Print full usage description.
[-d <file!> | --database=<file!>]     #  Database file with motifs.
[-c <uint>  | --cpus=<uint>]          #  Number of CPUs to use        -  Default=1
[-I <file!> | --stream_in=<file!>]    #  Read input from stream file  -  Default=STDIN
[-O <file>  | --stream_out=<file>]    #  Write output to stream file  -  Default=STDOUT
[-v         | --verbose]              #  Verbose output.

Examples

To locate the protein domains in the sequences in the FASTA file test.faa using hmmer_seq do:

read_fasta -i test.faa | hmmer_seq -d $BP_DATA/Pfam/Pfam-A.hmm
