NAME

Bio::Tools::Analysis::Protein::ELM

SYNOPSIS

# get a Bio::Seq object to start with, or a Bio::PrimaryI object.

my $tool = Bio::Tools::Analysis::Protein::ELM->
    new(seq => $seqobj->primary_seq() );	
$tool->compartment(['ER', 'Golgi']);
$tool->species(9606);
$tool->run;
my @fts = $tool->Result('Bio::SeqFeatureI');
$seqobj->addSeqFeature(@fts);

DESCRIPTION

This module is a wrapper around the ELM server (http://elm.eu.org/) which predicts short functional motifs on amino acid sequences. Two filters can be applied to help limit the rate of false positives: species and cellular compartment of the protein if known. The modules supply methods for setting these attributes. To set species attribute, use either a Bio::Species object or an NCBI taxon ID number. To set the cell compartment attribute (any number of compartments can be chosen) use an array reference to a list of compartment names. Results can be obtained either as raw text output, as parsed into a data structure, or as Bio::SeqFeature::Generic objects.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

compartment

name        : compartment
usage       : $elm->compartment(['golgi', 'er']);
purpose     : get/setter for cell compartment specifications
arguments   : None, single compartment string or ref to array of
                   compartment names.
returns     : Array of compartment names (default if not previously
                   set).

species

name      : species
usage     : $tool->species('9606');
purpose   : get/setter for species selction for ELM server
arguments : none, taxon_id or Bio::Species object
returns   : a string of the ncbi taxon_id

result

 name      : result
 usage     : $tool->result('Bio::SeqFeatureI');
 purpose   : parse results into sequence features or basic data format
 arguments : none    (retrieves raw text without html)
             a value (retrieves data structure)
             'Bio::SeqFeatureI' (returns array of sequence features)
					tag names are : {method=>'ELM', motif=>motifname,
                                     peptide => seqeunce of match,
                                     concensus=> regularexpression of match.
	.
 returns   : see arguments.
