Doesn't it mean “fractional_volume_to_evaluate“” is always equal to 100?Posted by: LSL000UD @ March 22, 2020, 7:41 a.m.
I'm very sorry for any confusion. This was a bug that should have a very minor impact on everyone's DVH scores (no one's ranking changed). We have fixed the evaluation script on CodaLab, which had the same bug, and we are reevaluated all the leaderboard scores.
We have also fixed the evaluation function on GitHub so that new participants won't be affected. We just removed the np.maximum function in line 127 of provided_code/dose_evaluation_class.py/. That is:
fractional_volume_to_evaluate = 100 - voxels_in_tenth_of_cc/roi_size * 100
Thank you for very much for catching this bug. Please let me know if you have any questions.
