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.

Title   : new
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.
