HUMAnN3.5 error with MetaPhlAn4

Hi community,

I run HUMAnN3.5 with MetaPhlAn4 in linux but get a error, here is error message in screen:

ERROR: The MetaPhlAn taxonomic profile provided was not generated with the expected database version. Please update your version of MetaPhlAn to at least v3.0.

These two software were installed by conda, an HUMAnN version is v3.5, MetaPhlAn version is 4.0.1 (24 Aug 2022), the database were download and config using humann_database and metaphlan --install. my command line was pasted below:

humann -i merge.fq -o sample --threads 30 --search-mode uniref90 --memory-use maximum --metaphlan-options “-t rel_ab_w_read_stats” --pathways unipathway

please tell me what’s wrong, I can’t fix it by myself.

PS. I have run humann_test and all thing is ok. I also have run MetaPhlAn4 separately, and it correctly worked, and same data was successfully tested using HUMAnN3.1 with MetaPhlAn3

Thanks,
Nemo

Is there any progress?

Hello Nemo, Thank you for the detailed post and for testing each tools install. Would you try running again without the MetaPhlAn option “-t rel_ab_w_read_stats”? I think that changes the format of the output file which might cause HUMAnN to have an issue trying to read the relative abundances (as they might be placed in a different column then expected).

Thank you,
Lauren

Hi Lauren,

you are right, i have run humann3.5 with default parameter using same data and it working, so this error is conducted by option ‘-t rel_ab_w_read_stats’.

Nevertheless, I still hope get reads count to do some difference analysis like deseq2 and ancom, could there any solution for this?i also could run humann3.5 and metaphlan4 separately, but it seemly complicated.

Thanks,
Nemo
