SILVA classifier for V3V4


I’d like to use SILVA to classify my sequences. I downloaded the SILVA reference from the Nov 2016 post and it doesn’t seem to be compatible with this release of qiime2.

qiime feature-classifier classify-sklearn --i-classifier Silva/silva-119-99-full-length-nb-classifier.qza --i-reads rep-seqsMerged_050317_270.qza --o-classification taxonomyMerged_050317_270SILVA.qza
Plugin error from feature-classifier:

  The scikit-learn version could not be determined for this artifact,
  please retrain your classifier for your current deployment to prevent
  data-corruption errors.

I’d prefer to train the classifier myself to my region (V3V4). Are the files to train the classifier available?

Hi @akknight216, the Nov 2016 post was for the 2.0.6 release of QIIME 2, which is no longer supported. You can grab the latest versions of the trained classifiers at the documentation site’s “Data resources” page.

As far as training your own classifier, we have a whole tutorial dedicated to the topic! Let us know if you have any questions. Thanks!
