[BioC] hyperGTest and HyperGParams

[João Fadista]

Dear all,
 
I would like to know if there is a way to use the hyperGTest function in the Category package if I don´t have an annotation package. I have the ensembl id´s of the genes in my microarray as well as all the GO terms associated with them.
 
If there is other tool that does the same job without the need of specifying the annotation package I will also be glad the hear about.
 
 
Best regards,
João Fadista
