Hi @RA2DREAMChallengeParticipants, The webinar recording is now available on the wiki [here](https://www.synapse.org/#!Synapse:syn20545111/wiki/599308). Also, if you didn't see it yet on the discussion forum, the 50-sample data subset is currently unavailable due to technical issues with UBRITE beyond the control of the challenge organizers. UAB is aware of the issue. We will provide an update when we learn more. Best, Robert
