It looks like there is an issue with the linked reference set file in the most recent version (at least 2024.5) of the Parkinson's Mouse Tutorial: https://data.qiime2.org/2024.5/common/sepp-refs-gg-13-8.qza. Wget gives a 404 error and does not work at all, and trying to upload using curl/direct file transfer seems to work, but then when you run the next step in the workflow (qiime fragment-insertion), it gives an error saying that the reference file is not a QIIME archive. I am able to run this step successfully using older versions of the reference file (i.e., 2023.5).
Apologies for the confusion here! We're currently in the middle of some classifier updates, and you've found an old URL that's no longer in use. Please use the following link instead:
I'm in the process of re-building our user docs today with the appropriate URL updates, so you should see everything up-to-date by end of day. Thanks for reaching out, let us know if you run into any other issues!
