Gotcha! Thanks @Nicholas_Bokulich for the clarification! I guess I'll just use the older version of qiime for downstream SCNIC analyses.

Hi @thermokarst

Following your advice, I tried installing QIIME 2 version 2018.11 from here:

But get the following error:

```

Any thoughts on why the packages are in conflict, since I'm downloading the version of qiime that the packages are supposedly a part of?

My guess is that bioconda and/or conda-forge have shuffled some of their packages around. I suggest you check out the VMs as a workaround. BTW - we are no longer supporting QIIME 2 2018.11, but you should still be able to download them:
