[BiO BB] GI numbers

[Stefanie Lager]

Try linking them through LocusLink, either using one of the mapping
tables found at: ftp://ftp.ncbi.nih.gov/refseq/LocusLink/ or (a bit more
complicaated) using a system like OpenBNS: http://openbns.sourceforge.net/

> 
> Sequence 14600509 is the protein coded by gene APE0180 from Aeropyrum
> pernix complete genome, as described in COG's table myva=gb. The same
> sequence is identified by GI 5103570 in Kegg. In this case, I was able
> map COG's GI to Kegg's GI by using the gene identifier and annotation,
> a procedure that is not easily automated.

> How can I retrive equivalent IDs for the whole COG gene set?
