Over the last decade, short-read DNA sequencing machines have delivered ever-larger data sets. Environmental microbiologists have used DNA sequencing to deeply sample microbial communities from many environments, including the ocean and soil. We have been working on computational techniques to slice and dice these data sets for over a decade, and recently we have made quite a bit of progress in approaches to investigating, analyzing, correlating, and exploring these data types; I’ll talk about using these tools to investigate the Tara Oceans data sets.  Needless to say, all of our tools are open source and readily available for use by others.


C. Titus Brown works at the UC Davis School of Veterinary Medicine, where his lab develops open-source tools and approaches for working with sequencing data. In 2014 he was awarded a Moore Data Driven Discovery Investigator award. Titus blogs at http://ivory.idyll.org/blog/ and tweets at @ctitusbrown.
