New paper shows that ~20% of taxonomy
annotations are wrong in SILVA and Greengenes.
New paper shows that taxonomy
prediction accuracy is <50% for V4 sequences.
PeerJ paper shows low
accuracy of closed- and open-ref. QIIME OTUs.
New paper 97% threshold
is wrong -- OTUs should be
99% full-length 16S, 100% for V4.
