Bio::Tools::Genscan - Results of one Genscan run $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(); 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 the Bio::SeqAnalysisParserI manpage.

Reporting Bugs
Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution. Bug reports can be submitted via email or the web: bioperl-bugs@bio.perl.org http://bio.perl.org/bioperl-bugs/ Email hlapp@gmx.net Describe contact details here 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.
