NAME

CCO::Parser::GoaParser - A GOA associations to OBO translator.

DESCRIPTION

Includes methods for adding information from GOA association files to ontologies GOA associations files can be obtained from http://www.ebi.ac.uk/GOA/proteomes.html

The method 'parse' parses the GOA association file and returns a CCO::Util::GoaAssociationSet object

The method 'work' incorporates OBJ_SRC, OBJ_ID, OBJ_SYMB, SYNONYM, DESCRIPTION into the input ontology, writes the ontology into an OBO file, writes map files. This method assumes: 1. the ontology contains already the term 'protein' 2. the ontology already contains all and only the necessary GO terms. 3. the ontology already contains the relationship types 'is_a', 'participates_in' 4. the input GOA association file contains entries for one species only and for GO terms present in the input ontology only
