HUMAnN filter out non-bacterial pathways and genes

Apologies if this has been asked before (I checked but couldn’t find much) but I am wanting to look at specifically bacterial pathways/genes on skin. How do I go about filtering this?

Some of the pathways are showing up as significant but I am not able to figure out where it came from? For example: PWY.3781…aerobic.respiration.I…cytochrome.c.


My recommendation would be to look at functions that are enriched on the skin relative to other body sites / environments. We did some work along those lines in this paper, and you could likely borrow some of the results from the supporting data / tables as a starting point:
