[Bioperl-l] GenBank ASN.1 SeqIO parser

[Chris Mungall]

Just to add to Barry's suggestions:

You can query the database directly:
http://www.berkeleybop.org/goose

You can also use the go-db-perl API and point it at the mysql port of  
one of the mirrors; see
http://www.geneontology.org/GO.database.shtml
