@William is in the process of preparing the Silva 132 QIIME-compatible release (thanks @William!), and we have prepared an initial version of the classifiers that can be used for testing purposes. It would be very helpful to get feedback from users of these classifiers to let us know if you’re experiencing any issues or if they’re working well for you (we’re interested in feedback either way). You can reply to this post with your feedback.
IMPORTANT: The Silva 132 QIIME-compatible release has not gone live yet, so you should use these classifiers only for testing or preliminary analyses. You’ll want to update your results to use classifiers trained on the official release when they are ready. We hope to have those classifiers available within the next couple of weeks.
UPDATE: The Silva 132 QIIME-compatible release is now live. There were no changes to the 99% OTUs since these classifiers were trained, so the classifiers posted here are based on the versions that are live on the Silva website. As the updated Silva files were just released, you should still be on the lookout for any issues (unexpected taxa, etc). As always, if something doesn’t seem right, look into it further (for example, by comparing classification results with BLAST results and/or classification against another reference database such as Greengenes) before assuming it’s right.
We’ll be updating this post to include some additional classifiers over the next week, so check back if you’re interested.
