An abbreviated (but still information-packed) version of the 2012 XNAT Workshop is going to be delivered in Munich on September 13-14, immediately following this year's INCF Neuroinformatics conference. There will be no cost for attendees, and registration is now available!
You can see the working agenda here, to see how much XNAT 1.6 goodness can be packed into a two-day span. The answer? A lot.
