=head1 NAME
Bio::Tools::Prediction::Exon - A predicted exon feature
=head1 SYNOPSIS
See documentation of methods.
=head1 DESCRIPTION
A feature representing a predicted exon. This class actually inherits
off Bio::SeqFeature::Gene::Exon and therefore has all that
functionality (also implements Bio::SeqFeatureI), plus a few methods
supporting predicted features, like various scores and a
significance. Even though these were inspired by GenScan results, at
least a subset should be generally useable for exon prediction
results.

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

# Let the code begin...

=head2 predicted_cds
Title : predicted_cds
Usage : $predicted_cds_dna = $exon->predicted_cds();
$exon->predicted_cds($predicted_cds_dna);
Function: Get/Set the CDS (coding sequence) as predicted by a program.
This method is independent of an attached_seq. There is no
guarantee whatsoever that the returned CDS has anything to do
(e.g., matches) with the sequence covered by the exons as annotated
through this object.
Example :
Returns : A Bio::PrimarySeqI implementing object holding the DNA sequence
defined as coding by a prediction of a program.
Args : On set, a Bio::PrimarySeqI implementing object holding the DNA
sequence defined as coding by a prediction of a program.
=cut
sub predicted_cds {
my ($self, $cds) = @_;
if(defined($cds)) {
$self->{'_predicted_cds'} = $cds;
}
return $self->{'_predicted_cds'};
}
=head2 predicted_protein
Title : predicted_protein
Usage : $predicted_protein_seq = $exon->predicted_protein();
$exon->predicted_protein($predicted_protein_seq);
Function: Get/Set the protein translation as predicted by a program.
This method is independent of an attached_seq. There is no
guarantee whatsoever that the returned translation has anything to
do with the sequence covered by the exons as annotated
through this object, or the sequence returned by predicted_cds(),
although it should usually be just the standard translation.
Example :
Returns : A Bio::PrimarySeqI implementing object holding the protein
translation as predicted by a program.
Args : On set, a Bio::PrimarySeqI implementing object holding the protein
translation as predicted by a program.
=cut
sub predicted_protein {
my ($self, $aa) = @_;
if(defined($aa)) {
$self->{'_predicted_aa'} = $aa;
}
return $self->{'_predicted_aa'};
}
=head2 significance
Title : significance
Usage : $evalue = $obj->significance();
$obj->significance($evalue);
Function:
Returns :
Args :
=cut
sub significance {
my ($self, $value) = @_;
return $self->_tag_value('signif', $value);
}
=head2 start_signal_score
Title : start_signal_score
Usage : $sc = $obj->start_signal_score();
$obj->start_signal_score($evalue);
Function: Get/Set a score for the exon start signal (acceptor splice site
or initiation signal).
Returns :
Args :
=cut
sub start_signal_score {
my ($self, $value) = @_;
return $self->_tag_value('AccScore', $value);
}
=head2 end_signal_score
Title : end_signal_score
Usage : $sc = $obj->end_signal_score();
$obj->end_signal_score($evalue);
Function: Get/Set a score for the exon end signal (donor splice site
or termination signal).
Returns :
Args :
=cut
sub end_signal_score {
my ($self, $value) = @_;
return $self->_tag_value('DonScore', $value);
}
=head2 coding_signal_score
Title : coding_signal_score
Usage : $sc = $obj->coding_signal_score();
$obj->coding_signal_score($evalue);
Function: Get/Set a score for the exon coding signal (e.g., coding potential).
Returns :
Args :
=cut
sub coding_signal_score {
my ($self, $value) = @_;
return $self->_tag_value('CodScore', $value);
}
