HI @R44H88,

The `ancombc2` functionality was not added until the `rachis-qiime2-2025.4 ` release. See the associated release announcement [here](https://forum.qiime2.org/t/qiime-2-2025-4-is-now-available/33088).

I'd suggest downloading the latest `rachis-qiime2-2026.7` release, as there have been two years of updates and improvements since `qiime2-amplicon-2024.10`.

-Cheers!
