I am trying to run a gene ontology analysis but my reference species is A.thaliana available here: org.At.tair.db. However, the function goana doesn't recognize species "At" and performs the GO enrichment against the human genome.
Kegga seems to recognize species "At" but I get the following error:
Error in kegga.default(de = DEGenes, universe = universe, ...) : Pathways do not overlap with universe
Please any help is much appreciated.
