Can I possibly use mpa_v30 on an older version of metaphlan?

[Marco_Severgnini]

Hello @Cheng_Li , I don’t know if you resolved your problem. Anyway, I think that latest versions of the databases are not backward compatible, as repoted here:

Most recent databases for Humann2

Hi all, I’m still running the “old” HUMAnN2 pipeline, but I suspect that reference databases are not up to date anymore. I’m wondering if and where I could find the updated chocophlan, Uniref and metaphlan databases (i.e.: the same used for HUMANn3, if compatible) to be used in HUMANn2. Thank you very much in advance Marco

Hope this helps.
