Mothur v.1.23.0

From mothur

We are happy to release our first offering of 2012 - mothur_v.1.23.0. This promises to be yet another exciting year for developing and supporting mothur!


The current release has a number of useful new commands and important feature updates that you will certainly want to check out. You may be interested in checking out two of the new commands. First, we have added yet another chimera detection approach - Persues - as chimera.perseus. Our testing suggests that it is about as good as chimera.uchime. Second, we also added shhh.seqs which is a sequence denoising algorithm originally developed by Chris Quince. We don't like it as well as pre.cluster, but feel free to play with it an form your own opinion. On the options front, we have continued to add parallelization to a number of commands for Windows users. We have also added q-values to the output from metastats so that the output is more in line with the original R code. Finally, we have updated the Schloss SOP, which reflects how my lab uses mothur to process sff files and was published recently in PLoS ONE and we have posted a mothur-compatible version of a greengenes-formatted taxonomy training set that contains >80k sequences.


As always, we appreciate your feedback, recommendations, and questions. We are planning on hosting another workshop in the Detroit area this April 23-25. If you are interested in attending, please email pdschloss@gmail.com to reserve your seat.
