Bio::OntologyIO::goflat(3pm)

NAME
Bio::OntologyIO::goflat - a parser for the Gene Ontology flat-file format

SYNOPSIS
  use Bio::OntologyIO;

  # do not use directly -- use via Bio::OntologyIO
  my $parser = Bio::OntologyIO->new
        ( -format       => "go",
     -defs_file    => "/home/czmasek/GO/GO.defs",
          -files        => ["/home/czmasek/GO/component.ontology",
                            "/home/czmasek/GO/function.ontology",
                            "/home/czmasek/GO/process.ontology"] );

  my $go_ontology = $parser->next_ontology();

  my $IS_A    = Bio::Ontology::RelationshipType->get_instance( "IS_A" );
  my $PART_OF = Bio::Ontology::RelationshipType->get_instance( "PART_OF" );

DESCRIPTION
Needs Graph.pm from CPAN.

This is essentially a very thin derivation of the dagflat parser.

  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.

 Usage   : $parser = Bio::OntologyIO->new(
                             -format => "go",
                             -defs_file => "/path/to/GO.defs",
                             -files => ["/path/to/component.ontology",
                                        "/path/to/function.ontology",
                                        "/path/to/process.ontology"] );
 Function: Creates a new goflat parser.
 Returns : A new goflat parser object, implementing Bio::OntologyIO.
 Args    : -defs_file  => the name of the file holding the term
                          definitions
           -files      => a single ontology flat file holding the
                          term relationships, or an array ref holding
                          the file names (for GO, there will usually be
                          3 files: component.ontology, function.ontology,
                          process.ontology)
           -file       => if there is only a single flat file, it may
                          also be specified via the -file parameter
           -ontology_name => the name of the ontology; if not specified the
                          parser will auto-discover it by using the term
                          that starts with a $, and converting underscores
                          to spaces
           -engine     => the Bio::Ontology::OntologyEngineI object
                          to be reused (will be created otherwise); note
                          that every Bio::Ontology::OntologyI will
                          qualify as well since that one inherits from the
                          former.
