XNAT Workshop in London: October 31 – November 4, 2022

The XNAT Team, in partnership with the Health and Bioscience IDEAS training program at University College London, with support from the Institute for Cancer Research UK, NCITA, SyneRBI, and Flywheel, are excited to announce a return to in-person workshops!


The goal of this workshop is to maximize the benefits of being able to meet in person. This means hands-on time with expert XNAT developers for newcomers and experienced stakeholders alike, coupled with the ability to discuss key topics relevant to XNAT's past, present, and future.
