enhanced parser for Signalp output

NAME

Bio::Tools::Signalp::ExtendedSignalp - enhanced parser for Signalp output

SYNOPSIS

 use Bio::Tools::Signalp::ExtendedSignalp;
 my $params = [qw(maxC maxY maxS meanS D)];
 my $parser = new Bio::Tools::Signalp::ExtendedSignalp(
                                                       -fh      => $filehandle
                                                       -factors => $params
                                                      );
 $parser->factors($params);
 while( my $sp_feat = $parser->next_feature ) {
       #do something
       #eg
       push @sp_feat, $sp_feat;
 }

DESCRIPTION

# Please direct questions and support issues to [email protected]

Parser module for Signalp.

Based on the EnsEMBL module Bio::EnsEMBL::Pipeline::Runnable::Protein::Signalp originally written by Marc Sohrmann (ms2 a sanger.ac.uk) Written in BioPipe by Balamurugan Kumarasamy (savikalpa a fugu-sg.org) Cared for by the Fugu Informatics team ([email protected])

You may distribute this module under the same terms as perl itself

Compared to the original SignalP, this method allow the user to filter results out based on maxC maxY maxS meanS and D factor cutoff for the Neural Network (NN) method only. The HMM method does not give any filters with 'YES' or 'NO' as result.

The user must be aware that the filters can only by applied on NN method. Also, to ensure the compatibility with original Signalp parsing module, the user must know that by default, if filters are empty, max Y and mean S filters are automatically used to filter results.

If the used gives a list, then the parser will only report protein having 'YES' for each factor.

This module supports parsing for full, summary and short output form signalp. Actually, full and summary are equivalent in terms of filtering results.
