[BioC] Gene orthologes lookup table

[Steffen Durinck]

Hi Simon,

I just wanted to add to Sean's suggestion that you should use the 1.9.29 
devel version of biomaRt (this will  be in BioC2.0).
Older versions of the package only retrieve the homolog id but not the 
query id where you started from.  So if you would query a list of ids at 
once you wouldn't be able to know to which of the query ids the homologs 
correspond to.  The devel version of the package returns both the query 
ids and their homologs.

Best,
Steffen
