Hi @macrobiome,

Have you tried using [q2-empress](https://library.qiime2.org/plugins/empress/32/)?

If needed, you can always use the [edit-taxonomy](https://forum.qiime2.org/t/processing-filtering-and-evaluating-the-silva-database-and-other-reference-sequence-data-with-rescript/15494#heading--sixteenth-header) action of [q2-rescript](https://github.com/bokulich-lab/RESCRIPt) to truncate the taxonomy strings in the taxonomy file, down to phylum, and use that.

_EDIT: Keep in mind, that taxonomy does not always map well to phylogeny._
