Bio::Tools::Signalp.3pm

NAME

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

SYNOPSIS

  use Bio::Tools::Signalp;
 
 

  my $parser = Bio::Tools::Signalp->new(-fh =>$filehandle );
 
 

  while( my $sp_feat = $parser->next_result ) {
    if ($sp_feat->score > 0.9) {
       push @likely_sigpep, $sp_feat;
    }
  }
 
 

DESCRIPTION

"SignalP" predicts the presence and location of signal peptide cleavage sites in amino acid sequences.

Bio::Tools::Signalp parses the output of "SignalP" to provide a Bio::SeqFeature::Generic object describing the signal peptide found, if any. It returns a variety of tags extracted from the NN and HMM analysis. Most importantly, the "score()" attribute contains the NN probability of this being a true signal peptide.
