Mothur v.1.33.0

We are happy to be releasing mothur v.1.33.0, which includes a number of exciting new features and updates. There is one new command - merge.sfffiles, which does the obvious. Among the new features in existing commands we have added the Square Root Jensen-Shannon Divergence and Jensen-Shannon Divergence calculators, which you can use to calculate distances between samples using "rjsd" and "jsd". These have been popular in some of the recent microbiome literature and thought you would appreciate having access to these. We have also added the ability to assign samples to community types in get.communitytype using K-means and PAM; however, we still recommend using DMM. Following up on some of the features in the last release that were based on the work of Curtis Huttenhower, we have added the picrust and reftaxonomy options to make.biom so that it is easier for mothur users to interface wihe picrust. Finally, there are a number of odds and ends that you'll see below mothur v.1.33.0#Feature updates.

We hope to have another release out to you in the next month or so with a really important new command. We have been working with the SRA at NCBI to create a mothur command that will prepackage everything to make uploadind data to the SRA easier. Those of you that we have spoken about are very excited about this. The folks at the SRA have been great about faciliating this and understanding the difficulties users are facing in getting their data up to the SRA.

If you haven't heard, I will be hosting another mothur-based workshop in Detroit on March 24-26. See the Workshops page for more information. There are still a few seats available. There will likely be another R workshop in June and mothur workshops in August and December.

Keep your great ideas coming and we'll do our best to work them into mothur!
