Just in case if someone else is looking for classifiers that are already trained on different regions or databases, I will share the link to the folder where I store them.
This folder can be updated by me, but the link is stable (at least for now).
For example, if you need the classifier for V4 region, silva 138.2 and qiime2 version 2024.10, then open folder q2_24-10/Silva138_2 and download files:
- classifier-V4.qza
- taxa-V4.qza
- seqs-V4.qza
V34 - V3-V4
V12 - V1-V2
V4 - V4
arch - Archaea
Exact primers can be found in the Jupyter notebook files.
ATTENTION_1: Organisation of that directory is a little bit chaotic since I never had a goal to train the classifiers for all regions and databases, as well as Qiime2 versions. I just put there classifiers that I used for my projects or trained for my colleagues.
ATTENTION_2: Classifiers are provided "as it is" and I am not responsible for any errors I did during the training. Use them at your own risk.
Best,
Timur
