Humann error database version

Microbial community profiling HUMAnN

Hi
I am using humann3 installed via conda. I have tried all the methods mentioned in the tutorials and forums, but still, I am facing a problem.

CRITICAL ERROR: The directory provided for ChocoPhlAn contains files ( utility_mapping ) that are not of the expected version. Please install the latest version of the database: 201901b
conda activate biobakery3m

(biobakery3) plankton@PlanktonEcology:/media$ humann_config

This the database which I am using /home/plankton/Humann_databases/uniref/uniref90_201901b_full.dmnd.

Thank you

Sorry for the slow reply. HUMAnN requires that its pangenome files of a given version (e.g. 201901b) be organized in a folder with only those pangenomes - no other files. It looks like you might have installed your utility mapping folder to the same location. We use this as a safety measure to make sure that users aren’t mapping to database files of different versions.
