I am trying to analyze the DE genes from rna-seq data, but when I try to use the goana function I get the error message "No annotated genes found in universe". I believe this is because the genes are annotated with the gene IDs from Ensembl instead of the ones from RefSeq. Nevertheless, I can still perform GO analyses with Ensembl ID with a different program, but I need a list of the DE genes so I can select them to proceed with the GO analyses. How can I get a list of the up and down regulated genes from the edgeR?
Best regards, Rodrigo.
