Hi @Angela1971,

You might make your life much easier by using [RESCRIPt](https://forum.qiime2.org/t/processing-filtering-and-evaluating-the-silva-database-and-other-reference-sequence-data-with-rescript/15494). ⌛

You can download whichever version of SILVA you'd like and process the database in your own way. This is the tool we use to generate the SILVA reference databases on the [Data resources](https://docs.qiime2.org/2020.11/data-resources/) page.

Take it for a spin and let us know how things work out. 🏎

-Mike
