Oh gosh, you're right! Sorry about that! 🤦‍♂️

It appears that the files are not included in the latest release... not sure why. You can download them from the prior release [here](https://docs.qiime2.org/2024.2/data-resources/#silva-16s-18s-rrna) Just be sure to click the "Show me content on this page". The files are identical, but you'll have to train the classifier for 2024.5 based on these input files.

I'd recommend simply using RESCRIPt as outlined [here](https://forum.qiime2.org/t/using-silva-138-pre-trained-classifier/30857/5), if you'd like to minimize any of the curation that was performed. Depending on what you are doing, the curation that was applied might be too agresive.
