Hello @EHRChallengeParticipants, We are pleased to announce that the Leaderboard Phase, Round 1, is officially open. You can submit your models to the ?EHR DREAM Challenge Submission? queue to be officially scored against UW data. If you want to test your models without running against the UW data, the ?EHR DREAM Challenge Fast Lane? will continue to be available. You will be allowed to have three successful submissions per round (9 total over the course of the challenge). If you submit a model and it breaks, that will not count toward your three. In the UW environment, your resources will be. 70 Gb RAM 4 Cores 6 Hours runtime Your submissions and their progress and scores will appear in this [dashboard](https://www.synapse.org/#!Synapse:syn18405991/wiki/595490) If you have questions or if the returned log files are vague, leave a comment in the discussion board and we will help debug your models. Good luck! EHR DREAM Challenge Admin Team
