Looking through the results, almost all pathways have names. For example PWY-6163 is chorismate biosynthesis from 3-dehydroquinate 0.999 But, when I look at PWY-4242, it is blank.

```

Checking MetaCyc website, it is not found unlike PWY-6163. Perhaps it has been removed for some special reason. How can I interpret this situation?

The newest HUMAnN (3.0.0) provided a big update to the MetaCyc pathway definitions; if you upgrade you will probably find them in better agreement with the modern MetaCyc website. Note that you don’t have to reprofile your samples from raw reads to update the pathways - you can rerun HUMAnN 3 starting from your genefamilies file as an input.

I should have mentioned that I used HUMAnN version 3.0.0 and this seemingly deprecated pathway was in the result.
