Hello!
I’ve been using HUMAnN 3.0 and I would like to use MaAsLin2 on the output file from HUManN.
I have completed the HUMAnN regroup, rename, renorm command and have the output as I need it.
Is there a way to combine the outputs? I have 8 samples, and therefore 8 HUMAnN outputs.
I saw this tutorial where they were combined in the “pathways\_norm.tsv” file. [https://github.com/karkman/MetagenomeCourse2019/blob/master/R\_for\_Humann2/pathways\_norm.tsv](https://github.com/karkman/MetagenomeCourse2019/blob/master/R_for_Humann2/pathways_norm.tsv)
Is this something I would need to write my own script for?
Thank you for your time!
Emily

There is a `humann_join_tables` script that I think solves the problem you’re posing here?

Thank you! I will try this!
For anyone else: I was able to merge everything in R.
I tried to delete my post after I figure it out, but I wasn’t able to!

No need to delete unless you really want to - this can still be useful to readers! 🙂
