When I accessed the Data resource page, the 'Silva 138 SSURef NR99 full-length sequences (MD5: de8886bb2c059b1e8752255d271f3010)' of the Silva (16S/18S rRNA) part were not downloaded.  
When I click on them, they don't download, and I get a '404 Not found' Page. Can you help me figure out why this is happening?

Hi @amirhoacid ,

The pre-trained classifiers have moved here:

> **[QIIME 2 Library](https://library.qiime2.org/)**

And discussion of this issue can be found here:

> Oh gosh, you're right! Sorry about that! man_facepalming 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 ar…

Good luck!
