Dear @BraTS2021ChallengeParticipants , Thank you all for participating! Today is the last day for submitting your segmentation files to the **BraTS Challenge - Task 1** evaluation queue! If you would like your segmentation files evaluated, please have them submitted **today, August 22nd, by 11:59 PM Eastern Standard Time**. Any submissions with a timestamp dated after this deadline will NOT be accepted. If you are experiencing scoring issues with your submissions, revisit your segmentations and ensure that: - the size is 240 x 240 x 155 - the origin is at [0, -239, 0] You can verify this by visualizing your predictions in [CaPTk](https://cbica.github.io/CaPTk/). Also, quick reminder that your [short paper](https://www.synapse.org/#!Synapse:syn25829067/wiki/611501) is **due Monday, August 23rd, at 10:00 AM Eastern Standard Time**. This short paper is **\*required\*** if you want to participate in next phase of submissions ([Docker submissions](https://www.synapse.org/#!Synapse:syn25829067/wiki/611500)), which will open on **Wednesday, Sept. 1st, at 11:59 PM Eastern Standard Time**. If you have any questions, please do not hesitate to continue using the Discussion Board to ask them. All the best, @BraTS2021ChallengeOrganizers
