I am using humann V .38 and Metaphlan version 4.06 (1 March 2023).

When I run this, it gives me an error "the metaphlan taxonomic profile provided was not generated with the database version v3 or VOct 22. Please update your version of metaphlan to 3.0 or if you are using metaphlan v4, please use the database vOct22.

When I use the command: \* ```  
humann\_databases --download chocophlan full /path/to/databases --update-config yes I get full\_chocophlan.v201901\_v31.tar.gz

Can someone PLEASE help?

Thank you in advance!

In case anyone needs this, I found it in the humann4 instructions: $metaphlan --install --index mpa\_vOct22\_CHOCOPhlAnSGB\_202403\*\*

Getting caught up here. Glad you were able to solve the problem based on the docs! 🙂

I did the same (metaphlan --install --index mpa\_vOct22\_CHOCOPhlAnSGB\_202403) but did not work out for me. Do I need to add anything after?

Hi @javadsadeghi, I do not know why when I pasted the command it put the ‘\*\*’ after the command. The way you have it looks correct. I used the exact command from the instructions for installing humann4 found here under how to set up the database: [HUMAnN 4.0.0.alpha.1 Release Notes - Google Docs](https://docs.google.com/document/d/1rCx5JkuO7wCKWrL8_-UJx_FkopJAfcDFtZktgPspak0/edit?tab=t.0)
