In addition to @Nicholas_Bokulich’s excellent reply, in answer to your questions regarding --o-classifier and --i-class-weight, the q2-feature-classifier and q2-clawback tutorials may be useful if you are training your own classifiers. The latter explains what --i-class-weight is for, but it is probably of academic interest only if you’re just getting started building data sets for a custom reference data set.
