As far as I can tell, it is trying to run with a database that does not exist.
This is the output:
Error message returned from metaphlan :

MD5 checksums not found, something went wrong!
I am trying to run the humann3 demo, I have the databases downloaded, the most current versions and as far as I can tell there is no mpa_v30_CHOCOPhlAn_201901b. How do I fix this?
Thank you in advance for your help.
