NAME

Bio::Tools::Analysis::DNA::ESEfinder - a wrapper around ESEfinder server

SYNOPSIS

use Bio::Tools::Analysis::DNA::ESEfinder;
use strict;

my $seq; # a Bio::PrimarySeqI or Bio::SeqI object

$seq = Bio::Seq->new(
     -primary_id => 'test',
     -seq=>'atgcatgctaggtgtgtgttttgtgggttgtactagctagtgat'.
     -alphabet=>'dna');

my $ese_finder = Bio::Tools::Analysis::DNA::ESEfinder->
    new(-seq => $seq);

# run ESEfinder prediction on a DNA sequence
$ese_finder->run();

die "Could not get a result"
    unless $ese_finder->status =~ /^COMPLETED/;

print $ese_finder->result;      # print raw prediction to STDOUT

foreach my $feat ( $ese_finder->result('Bio::SeqFeatureI') ) {

    # do something to SeqFeature
    # e.g. print as GFF
    print $feat->gff_string, "\n";
    # or store within the sequence - if it is a Bio::SeqI
    $seq->add_SeqFeature($feat)

}

DESCRIPTION

This class is a wrapper around the ESEfinder web server which uses experimentally defined scoring matrices to identify possible exonic splicing enhancers in human transcripts.

The results can be retrieved in 4 ways.

  1. $ese_finder->result('') retrieves the raw text output of the program

  2. $ese_finder->result('all') returns a Bio::Seq::Meta::Array object with prediction scores for all residues in the sequence

  3. $ese_finder->result('Bio::SeqFeatureI') returns an array of Bio::SeqFeature objects for sequences with significant scores. Feature tags are score, motif, SR_protein and method

  4. $ese_finder->result('raw') returns an array of significant matches with each element being a reference to [SR_protein, position, motif, score]

See http://exon.cshl.org/ESE/index.html

This the second implentation of Bio::SimpleAnalysisI which hopefully will make it easier to write wrappers on various services. This class uses a web resource and therefore inherits from Bio::WebAgent.
