mothur's blog

mothur is designed to help scientists to curate and analyze their 16S rRNA gene sequences. Frequently, there will be questions that come up where it would be helpful to demonstrate various concepts and processes. The code presented in this blog represents commands from mothur as well as in R. Here are some of the things we’ll cover at the blog…

Demo new features that have been incorporate into mothur
Describe how reference files were generated
Test ideas being bandied about in the literature
Respond to common or good questions that you email us

Another goal is to engage the community in a framework that supports reproducible science. These blog posts are not written as much as they are executed to generate their results. You can download all of the source code used to build this site at our github repository. There you can fork the repository and play around with our code to test various assumptions and modify the code to suit your needs.

Feb 23, 2021 README for the SILVA v138.1 reference files
The good people at SILVA have released a new version of the SILVA v138 database. My understanding is that this is a minor update to correct some taxonomic information. A little bit of tweaking is needed to get their files to be compatible with mothur. This README document describes the process that I used to generate the mothur-compatible reference files.
Feb 4, 2021 README for the RDP v18 reference files
The good people at the RDP have released a new version of the RDP database. A little bit of tweaking is needed to get their files to be compatible with mothur. This README document describes the process that I used to generate the mothur-compatible reference files. The original files are available from the RDPs sourceforge server and were used as the starting point for this README.
Mar 4, 2020 README for the SILVA v138 reference files
The good people at SILVA have released a new version of the SILVA database. A little bit of tweaking is needed to get their files to be compatible with mothur. This README document describes the process that I used to generate the mothur-compatible reference files.
Jan 10, 2018 README for the SILVA v132 reference files
The good people at SILVA have released a new version of the SILVA database. A little bit of tweaking is needed to get their files to be compatible with mothur. This README document describes the process that I used to generate the mothur-compatible reference files.
Mar 22, 2017 README for the SILVA v128 reference files
The good people at SILVA have released a new version of the SILVA database. A little bit of tweaking is needed to get their files to be compatible with mothur. This README document describes the process that I used to generate the mothur-compatible reference files.
