Request for Pre-trained SILVA V1–V3 Naive Bayes Classifier

[diksha_klair (diksha)]

Hi QIIME2 community,

I’m working on 16S rRNA amplicon sequencing using the V1–V3 region with the following primer pair:

Forward: AGAGTTTGATCMTGGCTCAG
Reverse: ATTACCGTGGCTGCTGG

I'm using QIIME 2 version 2024.10 and would like to request a pre-trained Naive Bayes classifier trained on the SILVA 138/138.1 99% OTUs database, compatible with this region.

I attempted to train a custom classifier locally, but encountered memory issues. If a compatible .qza file is available, I’d really appreciate access to it.

Thank you so much for your time and help!

Best regards,
Diksha

Hi @diksha_klair ,
You can use the pre-trained classifiers for full-length 16S, which are available here:

QIIME 2 Library

The full-length classifiers will be suitable for any of the V-regions contained within the 16S.

Good luck!
