Hi,
I am sorry if I missed a solution to my problem, but I cannot find it in the previous forum.
I got gene families.tsv file from running Humann (v3.7) and ‘uniref90\_201901b\_full.dmnd’ was used as reference database. Then, I tried to rename the UniRef90 ID to EC or MetaCyc ID with the following code line. `humann_rename_table --input merged_knead_2102420018_genefamilies.tsv --output ./rename_test.tsv --names metacyc-pwy`, and I have got a message: `Renamed 0 of 178911 entries (0.00%)`.
I even confirmed that `UniRef90_A0A1F3ZUU1`, which is the L-lacate dehydrogenase (EC 1.1.1.27), in my gene families.tsv file, whereas this was also renamed as No\_name.
Is this phenomenon due to the extension of UniRef90 ID such as UniRef90\_ **A0A1F3** _ZUU1_ (extension in italics)? or I missed something?
I appreciate your help in advance.
Gihyeon.

The `rename` script is used to attach human-readable names (e.g. “Cyclin-dependent Kinase 1”) to systematic IDs (e.g. “UniRef90\_ABC”). To group genes into broader functional categories you would use the `regroup` script instead. Note that you cannot directly regroup genes to pathways, but you can regroup them to ECs or MetaCyc reactions (or KOs, Pfams, GO terms, etc.).
