[Bioperl-l] GenBank ASN.1 SeqIO parser

[Barry Moore]

Ryan,

I you have a list of NCBI Gene IDs then you can grab the flatfile  
gene2go from NCBIs ftp site ftp://ftp.ncbi.nlm.nih.gov/gene/DATA/ 
gene2go.gz.  That will give you tax_id, gene_id, go_id, evidence  
code, qualifier, category etc.  From there  you can get the  
description from the GO OBO file http://www.geneontology.org/ontology/ 
gene_ontology_edit.obo.  If all you need is the description then the  
file is pretty easy to parse on the fly, but if you need to traverse  
the graphs or if you want an already written parser then add go-perl  
http://search.cpan.org/~cmungall/go-perl/go-perl.pod
