Reboot

In July 2015, our laboratory will move to Harvard University. I've accepted an offer to join Harvard's faculty in two departments: Molecular & Cellular Biology (in the Faculty of Arts and Sciences), and Applied Mathematics (in the School of Engineering and Applied Sciences). The laboratory will be on the first floor of the venerable, historic … Continue reading Reboot

Dfam: annotation of transposable elements with profile HMMs

We're happy to announce the release of Dfam 1.0, a set of profile HMMs for genomic DNA annotation of transposable elements. This essentially constitutes an upgrade of repeat element annotation from using searches with single sequence consensuses to using searches with profile HMMs, now that the HMMER3 project has made DNA/DNA profile HMM searches sufficiently … Continue reading Dfam: annotation of transposable elements with profile HMMs

Infernal 1.1: RNA alignment and database search, 10,000x faster

One of our lab's goals is to make it possible to systematically search for homologs of RNAs in genomes, not just by looking for sequence conservation but also by looking for RNA secondary structure conservation. A powerful model framework for RNA structure/sequence comparison, called profile stochastic-context free grammars (profile SCFGs), was introduced in the mid-1990s … Continue reading Infernal 1.1: RNA alignment and database search, 10,000x faster
