NAME

Bio::Tools::Geneid - Results of one geneid run

SYNOPSIS

   use Bio::Tools::Geneid;
   my $gid = Bio::Tools::Geneid(-file => "geneid.out");
 
   while (my $gene = $gid->next_prediction)
   {
     my @transcripts = $gene->transcripts;
       foreach my $t (@transcripts)
       {
         my @exons = $t->exons;
         foreach my $e (@exons)
         {
           printf("Exon %d..%d\n", $e->start, $e->end);
         }
       }
   }
 
 

DESCRIPTION

This is the parser for the output of geneid by Enrique Blanco and Roderic Guigo (IMIM-UPF). See http://www1.imim.es/software/geneid. It relies on native geneid output format internally and will work with geneid versions 1.0 and 1.1. Currently this module supports only the default mode of operation which is to predict exons and assemble an optimal gene prediction.

It takes either a file handle or a file name and returns a Bio::SeqFeature::Gene::GeneStructure object.

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 _

new

  Title   : new
  Usage   : $obj->new(-file = "<geneid.out");
            $obj->new(-fh => \*GI);
  Function: Constructor for geneid wrapper. Takes either a file
          : or filehandle
  Returns : L<Bio::Tools::Geneid>
 
 

next_prediction

  Title   : next_prediction
  Usage   : while($gene = $geneid->next_prediction)
            {
                # do something
            }
  Function: Returns the gene structure prediction of the geneid result
            file. Call this method repeatedly until FALSE is returned.
  Returns : A Bio::SeqFeature::Gene::GeneStructure object
  Args    : None
 
 

_add_exon

  Title   : _add_exon
  Usage   : $obj->_add_exon($gene, $transcript, ... exon data ...)
  Function: Adds a new exon to both gene and transcript from the data
          : supplied as args
  Example :
  Returns : Nothing
 
 

_set_strand

  Title   : _set_strand
  Usage   : $obj->_set_strand($gene)
  Function: Sets the overall gene strand to the same strand as all
          : the exons if they are all on the same strand, or to strand 0
          : if the exons are on different strands.
  Example :
  Returns : Nothing
 
 

_target_id

  Title   : _target_id
  Usage   : $obj->_target_id
  Function: get/set for genomic sequence id
  Example :
  Returns : A target ID
