Built environment researchers from all over the country got together last week to improve the functionality of two of the most commonly-used bioinformatics pipelines, QIIME and VAMPS, and to facilitate data sharing. Rob Knight and Mitch Sogin were on hand to discuss current capabilities of the software packages, and Greg Caporaso wrapped up the meeting with an excellent tutorial for using QIIME on the Amazon Cloud. Researchers from the major built environment labs each presented current bioinformatics approaches and challenges, including James Meadow (BioBE Center), who discussed our most recent findings from the Lillis Business Complex Project. MicroBEnet has aggregated presentation slides and videos on their blog.
