Difficult to say.

Is there a reason why you link to the fasta file from the SILVA web site? The name you provide does not match the file name in the link. Was this intended?

I guess I'd need more details on how the reference data is handled and/or further processed within R prior to classification. I am unfamiliar with how this tool and its commands (e.g. `makeTaxonomyFasta_SilvaNR`) works. So, I'd suggest classifying through QIIME 2 for a comparison and sanity-check. 🤷‍♂️

I assume you followed all of the "Make amplicon-region specific classifier" parts of the RESCRIPt tutorial? That is, the sequence and taxonomy dereplication steps, prior to importing them into R? Just asking to make sure I understand all the steps you've taken. 🙂

Check out this thread: [training classifiers: performance of full-length vs. extract-reads](https://forum.qiime2.org/t/training-classifiers-performance-of-full-length-vs-extract-reads/14138) for some additional insights.

Do you have anything to add, @Nicholas_Bokulich ?
