From a quick search on the forum and the q2-feature-classifier plugin, it doesn’t seem like the RDP classifier is supported by QIIME 2.
Coming from the perspective of a curmudgeony microbiome researcher switching into QIIME 2, this is pretty unfortunate. What’s the reasoning behind not including it? Is it installation issues (would need to download RDP from SourceForge) or something about the fact that you need java to run it?
If there aren’t any particularly hairy technical reasons why this hasn’t been included, I’d be happy to give it a shot. But before diving into an endless rabbit hole, wanted to make sure I’m caught up with whatever discussions y’all had on this topic!
