[BioC] Error GOseq

[Biase, Fernando]

Hi ,

I have tried to run GOseq on my differential expressed gene list, but when I try to run the following command:

GO.wall <-goseq(DEGgenes, pwf, "bosTau4", "ensGene", method= "Wallenius")

I get the following error:

Error in pwf$DEgenes : $ operator is invalid for atomic vectors

Does anyone has experience in solving this issue?

Thanks,
Fernando
