NCycDb, MCycDB, dbCAN2

Hello! I’m wondering if it’s possible to add NCycDB, MCycDB and dbCAN2 databases as part of the HUMAnN pipeline? I’m trying to get a more curated list of gene families, that is more related to biogeochemical pathways to determine the influence of microbiomes on ecosystem functions.

It looks like NCycDB and MCycDb have fasta files available that could potentially be used in DIAMOND using this code ./diamond makedb --in reference.fasta -d reference, but I’m not so sure about dbCAN2. I would really appreciate if anybody has any advice for this, or experience doing this and could direct me to relevant answers.

Best wishes,
