In enrichGO, BP subontology doesn't work, but CC ontology does?

Question

[cthangav]

I have been following this tutorial: Introduction to ChIP-Seq using high-performance computing Tutorial.

However my dataset is for mouse not human, so I am using the following mouse databases: TxDb.Mmusculus.UCSC.mm10.knownGene, EnsDb.Mmusculus.v79, and org.Mm.eg.db.

Here is the code I used:

ego <- enrichGO(gene = entrez, keyType = "ENTREZID", OrgDb = org.Mm.eg.db, ont = "BP", pAdjustMethod = "BH", qvalueCutoff = 0.05, readable = TRUE)

When I use this enrichGO command to find enriched genes, I get "0 enriched genes found". If I view ego, I get:

> ego
# over-representation test
#
#...@organism    Mus musculus
#...@ontology    BP 
#...@keytype     ENTREZID
#...@gene    chr [1:191] "50790" "17954" "23963" "107376" "66673" "546723" "17254" ...
#...pvalues adjusted by 'BH' with cutoff <0.05
#...0 enriched terms found
#...Citation

The ego term looks like this in R studio:

When I change 'ont' argument to CC, it works. Ideally I'd like to get BP to work, as those are the terms I need.

The object entrez (which I used enrichGO on) contains these Gene IDs (which are tab delimited in the object):

I noticed it works when I change 'ont' argument from BP (biological process) to CC (cellular component), but ideally I'd like to get the BP ontology to work.
