Hello,
I have installed the amplicon-2025.10 release and looked into the `q2-composition` plugin to see whether a interface change in the `da-barplot` methods made it to the new release 🙂
From coming up next in 2025.4:
- The `ancombc2-visualizer` action will be removed, in favor of `da-barplot`.
- `da-barplot` will be updated to produce the visualization now produced by `ancombc2-visualizer`, and it will be updated to accept results of `ancombc` and `ancombc2` as inputs.
I tested the 2025.10 da-barplot with my data and got this warning:
`/home/NAME/miniconda3/envs/qiime2-amplicon-2025.10/lib/python3.10/site-packages/unifrac/` **`init`** `.py:9: UserWarning: pkg_resources is deprecated as an API. See ` [https://setuptools.pypa.io/en/latest/pkg\_resources.html](https://setuptools.pypa.io/en/latest/pkg_resources.html) `. The pkg_resources package is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81.`
`import pkg_resources`
I assume that this is unrelated to `da-barplot` since the output visualization is created and it is in the old layout. I assume that a da-barplot update has not made into the 2025.10 release.
This gives me the chance to ask for a minor improvement in an updated `da-barplot` plugin/method. Since the `ancombc2-visualizer` features will go into the update (as stated above), may I suggest to expand the subset features options in a way that `lfc (log fold changes)` can be filtered in both directions at the same time (e.g. `lfc greater than 2 OR lfc less than -2`) either be allowing an **OR** operator or by allowing the **absolute value** (`lfc greater than |2|`).
Best regards,

Hello @arwqiime,
Sorry for the delay on this. We have an issue for the absolute value request [here](https://github.com/qiime2/q2-composition/issues/157), apologies that that wasn't possible already. We'll plan to get it done some time during this release.
The renaming of `ancombc2-visualizer` to `da-barplot` has become somewhat deprioritized due to the effort required to make `ancombc2-visualizer` compatible with the older `ancombc` output formats, but we are still planning to get around to it eventually.
Thanks,
Colin

Right now, having to run the visualizer twice (once for positive, once for negative) or manually filtering the feature table beforehand adds unnecessary friction when you just want a quick overview of the strongest drivers.

@jakabaesj10, we agree - we're working on a fix for this.
