Hey mothur users,

We’re happy to announce the release of v.1.38.0! This release primarily has a bunch of random bug fixes that we were anxious to get out to you. Two new commands should strike your interest. First, we have introduced rename.file, which renames files so that you don't have to worry about using your system commands and updates the "current" files. Second, building off the introduction of VSEARCH functionality in the last release, we've created chimera.vsearch to detect chimeras using VSEARCH. Their benchmarking indicates that it performs similar to UCHIME, which is available as chimera.uchime.

In addition to improvements to mothur, since the last release we've also published several papers and blog posts that you should definitely check out.
