Taking a quick look at the sample accession, I think this is shotgun metagenomics data?

If so that's the problem. DADA2 is designed for amplicon data, not shotgun data, and is likely to break in various ways due to its assumptions being violated.

Is there a Q2 plugin for shotgun data processing now?
