[DAS] US DAS workshop

Mon Feb 7 16:58:17 UTC 2011

Hmm...

There's the Genome Informatics meeting in August at CSHL ( http://meetings.cshl.edu/meetings/info11.shtml).  It's not the bay area and the organizers might already have a set program.  There is a "Databases, Data Mining, Visualization and Curation" session by Alex Bateman and Ting Wang though.

Hi,

Same for us here at UNC Charlotte.

Meetings I'm attending next include two major plant science meetings
(Arabidopsis and ASPB) and possibly ISMB in Vienna.

David are there any other meetings you and your group are planning to
attend?

The ideal setting would be a meeting where we can do outreach and hold
workshop event(s) for users, but also have a developers meeting where we
discuss future directions for the software, DAS spec, etc.

Are there other meetings that would be a good fit?

Best,

Ann
