Dear Bioconductor team, I have already built a design platform using Oligo package with XYS files, so I can identify some DEG's. Now, I would do a GO term enrichment analysis using GeneAnswers. However, I am a little bit confusing about the annotation package, in the GeneAnswers vignette I read I have to use a specific library with RefSeq, GeneID ... the same as library("org.Dm.eg.db"). How can obtain it from Mycobacterium tuberculosis ? If somebody could help me, it would be very apperciate.
