NAME
Bio::Tools::Genscan - Results of one Genscan run
SYNOPSIS
use Bio::Tools::Genscan; $genscan = Bio::Tools::Genscan->new(-file => 'result.genscan'); # filehandle: $genscan = Bio::Tools::Genscan->new( -fh => \*INPUT ); # parse the results # note: this class is-a Bio::Tools::AnalysisResult which implements # Bio::SeqAnalysisParserI, i.e., $genscan->next_feature() is the same while($gene = $genscan->next_prediction()) { # $gene is an instance of Bio::Tools::Prediction::Gene, which inherits # off Bio::SeqFeature::Gene::Transcript. # # $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 = $gene->exons('Terminal'); # singleton exons: ($single_exon) = $gene->exons(); } # essential if you gave a filename at initialization (otherwise the file # will stay open) $genscan->close();
DESCRIPTION
The Genscan module provides a parser for Genscan gene structure prediction output. It parses one gene prediction into a Bio::SeqFeature::Gene::Transcript- derived object. This module also implements the Bio::SeqAnalysisParserI interface, and thus can be used wherever such an object fits. See Bio::SeqAnalysisParserI.
FEEDBACK
Mailing Lists User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated. bioperl-l@bioperl.org - General discussion http://bioperl.org/wiki/Mailing_lists - About the mailing lists Support Please direct usage questions or support issues to the mailing list: bioperl-l@bioperl.org rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible. Reporting Bugs Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution.

APPENDIX
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _ analysis_method Usage : $genscan->analysis_method(); Purpose : Inherited method. Overridden to ensure that the name matches /genscan/i. Returns : String Argument : n/a next_feature Title : next_feature Usage : while($gene = $genscan->next_feature()) { # do something } Function: Returns the next gene structure prediction of the Genscan result file. Call this method repeatedly until FALSE is returned. The returned object is actually a SeqFeatureI implementing object. This method is required for classes implementing the SeqAnalysisParserI interface, and is merely an alias for next_prediction() at present. Example : Returns : A Bio::Tools::Prediction::Gene object. Args : next_prediction Title : next_prediction Usage : while($gene = $genscan->next_prediction()) { # do something } Function: Returns the next gene structure prediction of the Genscan 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 : $obj->_has_cds() Function: Whether or not the result contains the predicted CDSs, too. Example : Returns : TRUE or FALSE _read_fasta_seq Title : _read_fasta_seq() Usage : ($id,$seqstr) = $obj->_read_fasta_seq(); Function: Simple but specialised FASTA format sequence reader. Uses $self->_readline() to retrieve input, and is able to strip off the traling description lines. Example : Returns : An array of two elements.
