Bio::OntologyIO::goflat - a parser for the Gene Ontology flat-file format
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" );
Needs Graph.pm from CPAN.
This is essentially a very thin derivation of the dagflat parser.
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing lists Your participation is much appreciated.

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