This is a fantastic tutorial, thanks!  
I have a quick question. I want to use the silva reference with the 12-rank taxonomy, not the 7-rank like this tutorial references. I can't figure out where in the pipeline I need to make changes to address this, though. I feel like it's somewhere in the filtering, but I don't know what to add or remove to clarify this. Can you help me?

Thanks in advance!!

Hi @aeriel.belk,

We had recently updated our SILVA taxonomy parser to allow you to select the exact taxonomy ranks you'd like to use via the `--p-ranks` flag. You can select these ranks for either the `parse-silva-taxonomy` or `get-silva-data` actions:

 ![ranks](https://forum-qiime2-org.s3.dualstack.us-west-2.amazonaws.com/original/2X/6/6ee53ea93f85fb0d1db13a572ef4f280c95ca990.png)

That is, you can use this flag like so:

```auto
qiime rescript get-silva-data \
    --p-rank-propagation \
    --p-include-species-labels \
    --p-ranks domain kingdom phylum class subclass order family genus \
    --output-dir ... 

```

or

```auto
qiime rescript parse-silva-taxonomy \
    --p-rank-propagation \
    --p-include-species-labels \
    --p-ranks domain kingdom phylum class subclass order family genus \
    --output-dir ... 

```

You can re-install RESCRIPt following the instructions [here](https://github.com/bokulich-lab/RESCRIPt). _Note you'll need to be running QIIME version 2020.8._

I hope to update parts of the tutorial soon.

-Let us know how it goes!

Wow, thanks for getting back to me so quickly! That seems like a really easy fix, I'll try it right now 🙂
