We meet monthly to discuss tools used for metagenomic analysis. We discuss everything from software installation to output interpretation, on a tool-by-tool basis. We meet on the 3rd Friday of every month in the Genome Center at UC Davis. We post the paper up for discussion a week in advance, and encourage everyone who attends to read the paper and (if possible) install the software and run the tool. We provide a small test data set, appropriately formatted for each tool, on the Resources page.
