Registration is open for a conference on "Biological sequence analysis and probabilistic models", 24-27 March 2013, here at Janelia Farm. Katie Pollard (UCSF), Adam Siepel (Cornell), and I are the co-organizers. Janelia Farm conferences are small (\~50 people), a nice size for conversation and thought. We're likely to select about 15 more participants from open registration. For more information, including a current list of the invited speakers and a link to registration, see the Janelia conferences web page.
