omegaMap at BioHPC

All evolutionary biologists wishing to make use of omegaMap now have access to a high performance parallel computing cluster via the internet courtesy of Cornell's CBSU and Microsoft. The software, which allows the detection of selection and recombination in DNA or RNA sequences, can be run via the web interface at cbsuapps.tc.cornell.edu/omegamap.aspx, or downloaded as part of the BioHPC suite.

The web interface consists of a simple form where users can upload their configuration file and sequences in FASTA format. Completed jobs are notified by e-mail. To learn more about the project visit the CBSU home page.

Meanwhile, I am working on several major updates to omegaMap, the most interesting of which will probably be the development of a new model that allows for the joint analysis of natural selection acting on sequences from different populations or species. The aim is to integrate population genetic and phylogenetic models of selection in order to exploit the signal of selection contained both in polymorphism within populations (or species) and divergence between them. I will be presenting progress on this work, in the context of hominid evolution, at the 2009 SMBE meeting in Iowa City this June.
