[BioC] topGO spurious GO terms?

[Adam [guest]]

I am using topGO's custom workflow to get enrichment of GO terms. In my top 20 nodes there are significant GO terms that are not found in my "universe". I am new to analyzing GO information and I can only assume that these spurious GO IDs are part of pathways of GO IDs in my universe and are significant by association? Alternatively, topGO has a more updated list of GO IDs and has substituted the names in my universe. Any advice would be greatly appreciated!
