12-Jun-2018 New paper shows that one in five taxonomy annotations in SILVA and Greengenes are wrong.

18-Apr-2018 New paper shows that taxonomy prediction accuracy is <50% for V4 sequences.

05-Oct-2017 PeerJ paper shows low accuracy of closed- and open-ref. QIIME OTUs.

22-Sep-2017 New paper shows 97% threshold is wrong, OTUs should be 99% full-length 16S, 100% for V4.

USEARCH v11

Clustering using local alignment

Some programs, notably BLASTCLUST, perform clustering based on pair-wise local alignments. I believe the approach of local clustering is fundamentally flawed for most applications, so USEARCH does not support it. If you have an application that really does need local clustering, I will be glad to add it to USEARCH.
