[Gofriends] July 2009 GOA release

[Daniel Barrell]

GOA releases: July 2009
===========================

GOA (GO Annotation at EBI) is a project run by the European Bioinformatics
Institute that provides assignments of gene products to the Gene
Ontology (GO) resource.

The data can be obtained via:

            EBI FTP: ftp://ftp.ebi.ac.uk/pub/databases/GO/goa/

            EBI SRS: http://srs.ebi.ac.uk. Search GOA data library

            GO FTP: ftp://ftp.geneontology.org/pub/go/gene-associations/

            GO CVS: http://www.geneontology.org/GO.CVS.help.html

For further information read: http://www.ebi.ac.uk/GOA or contact

Important News about file format changes:
=========================================

Previously, annotation lines produced by electronic methods (as 
indicated by the presence of the 'IEA' evidence code in column 7) 
contained two identifiers piped together in the reference column; an 
internal GOA keyword (e.g. GOA:interpro) and a GO reference identifier 
(e.g. GO_REF:0000002). As of this file release, the GOA internal 
reference (e.g. GOA:interpro) and pipe has been removed from this field, 
so that only a GO_REF identifier is provided.

Full descriptions of the methods referenced by a GO reference identifier 
can be found at:  http://www.geneontology.org/cgi-bin/references.cgi

This format change effects all annotation lines that  had the following 
reference field contents:

GOA:interpro|GO_REF:0000002
GOA:hamap|GO_REF:0000020
GOA:spkw|GO_REF:0000004
GOA:spec|GO_REF:0000003
GOA:compara|GO_REF:0000019
GOA:spsl|GO_REF:0000023


We are also pleased to announce that  column 1 of the gene association 
files 'DB' now differentiates (where possible) between UniProt/TrEMBL 
and UniProt/Swiss-Prot.
