New Go Terms After Topgo Enrichment?

Question

[biotech]

Hi there,

I ran an enrichment analysis with custom annotations using TopGO and surprisingly I obtained new GO terms inside the significant GO terms.

Is that possible? The only reason I can imagine this is possible is because TopGO adds new GO terms based on the input GO terms, since GO ontology is structured hierarchically.

Please let me know if you need more details about the experiment.

These new GO terms seem to be the parents of the already GO terms present in my original dataset.
