Dear challenge participants, we've noticed that the docker to singularity conversion we do internally can cause problems for some teams, so that they need a few additional submissions. Therefore, we will still accept **docker submissions for task 2** until July 17, 23:59 (EDT). For the sake of fairness, only teams who have already submitted before the original submission deadline will be allowed to submit their fixed docker containers during this time. Thanks to all teams for their interest, we look forward to your task 2 submissions :)
