NAME ^

Bio::Tools::MZEF - Results of one MZEF run

SYNOPSIS ^

   $mzef = Bio::Tools::MZEF->new(-file => 'result.mzef');
   # filehandle:
   $mzef = Bio::Tools::MZEF->new( -fh  => \*INPUT );
   # to indicate that the sequence was reversed prior to feeding it to MZEF
   # and that you want to have this reflected in the strand() attribute of 
   # the exons, as well have the coordinates translated to the non-reversed
   # sequence
   $mzef = Bio::Tools::MZEF->new( -file   => 'result.mzef',
                                  -strand => -1 );

   # 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 = $mzef->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();

       # internal exons only
       @intrl_exons = $gene->exons('Internal');
       # note that presently MZEF predicts only internal exons!
   }

   # essential if you gave a filename at initialization (otherwise the file
   # will stay open)
   $mzef->close();

DESCRIPTION ^

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

This module inherits off Bio::Tools::AnalysisResult and therefore implements 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.

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.

APPENDIX ^

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

analysis_method

 Usage     : $mzef->analysis_method();
 Purpose   : Inherited method. Overridden to ensure that the name matches
             /mzef/i.
 Returns   : String
 Argument  : n/a

next_feature

 Title   : next_feature
 Usage   : while($gene = $mzef->next_feature()) {
                  # do something
           }
 Function: Returns the next gene structure prediction of the MZEF 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.

           Note that with the present version of MZEF there will only be one
           object returned, because MZEF does not predict individual genes
           but just potential internal exons.
 Example :
 Returns : A Bio::Tools::Prediction::Gene object.
 Args    :

next_prediction

 Title   : next_prediction
 Usage   : while($gene = $mzef->next_prediction()) {
                  # do something
           }
 Function: Returns the next gene structure prediction of the MZEF result
           file. Call this method repeatedly until FALSE is returned.

           Note that with the present version of MZEF there will only be one
           object returned, because MZEF does not predict individual genes
           but just potential internal exons.
 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
