SYNOPSIS

$grail = Bio::Tools::Grail->new(-file => 'result.grail');
# filehandle:
$grail = Bio::Tools::Grail->new( -fh => \*INPUT );
# parse the results
while($gene = $grail->next_prediction()) {
# $gene is an instance of Bio::Tools::Prediction::Gene
# $gene->exons() returns an array of
# Bio::Tools::Prediction::Exon objects
# all exons:
@exon_arr = $gene->exons();
# initial exons only
@init_exons = $gene->exons('Initial');
# internal exons only
@intrl_exons = $gene->exons('Internal');
# terminal exons only
@term_exons = $gene->exons('Terminal');
# singleton exons only -- should be same as $gene->exons() because
# there are no other exons supposed to exist in this structure
@single_exons = $gene->exons('Single');
}
# essential if you gave a filename at initialization (otherwise the file
# will stay open)
$genscan->close();

DESCRIPTION

The Grail module provides a parser for Grail gene structure prediction output.

APPENDIX

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

next_prediction

 Title   : next_prediction
 Usage   : while($gene = $grail->next_prediction()) {
                  # do something
           }
 Function: Returns the next gene structure prediction of the Grail result
           file. Call this method repeatedly until FALSE is returned.
 Example :
 Returns : A Bio::Tools::Prediction::Gene object.
 Args    :

_parse_predictions

 Title   : _parse_predictions()
 Usage   : $obj->_parse_predictions()
 Function: Parses the prediction section. Automatically called by
           next_prediction() if not yet done.
 Example :
 Returns :

_prediction

 Title   : _prediction()
 Usage   : $gene = $obj->_prediction()
 Function: internal
 Example :
 Returns :

_add_prediction

 Title   : _add_prediction()
 Usage   : $obj->_add_prediction($gene)
 Function: internal
 Example :
 Returns :

_predictions_parsed

 Title   : _predictions_parsed
 Usage   : $obj->_predictions_parsed
 Function: internal
 Example :
 Returns : TRUE or FALSE

_has_cds

 Title   : _has_cds()
 Usage   : $obj->_has_cds()
 Function: Whether or not the result contains the predicted CDSs, too.
 Example :
 Returns : TRUE or FALSE
