[BioC] enrichment + topGO

[Maryam]

Hi

I am trying to use topGO but I have problems using a list of gene names 
as I dont know which annotation function I should use for that and what 
would be the respective parameters for that. It would be nice if I could 
find samples of using topGO with ENSEMBL ids or gene names.

Apart from this issue, I want to change topGO in a way that it can 
accept other ontologies rather than GO.
Has anyone know how to do that?

Regards
Maryam
