Hi @John ,

@John

Is it OK that the taxonomy file contains entries that are not in the corresponding sequences file?

Yes this is not a problem (and is quite typical, actually, after filtering out sequences for one reason or another). The extra lines in the taxonomy will just be ignored by most actions.

If you ever run into a situation where the taxonomy and sequences must match exactly (there are a few rare actions that require this), you can use RESCRIPt to filter your taxonomy as shown in this tutorial (see the filter-taxa action):
