Dear abhiroopt,
Thank you for reaching out to us.
You indeed discovered a mistake in the code that you are referring to. The score_patient function should indeed not create a mask of ones, but read the provided mask. I will correct this mistake on this github page.
However, the score_patient function is only written to make the code for the metrics readable for the participants. The evaluation on the grand challenge platform consists of a bigger code reading in the patient data. I double checked, and the error was not in the official code, and for the mask we read in the provided mask.
I hope this answers your question.
Good luck with the preparations.
Best regards,
Evi
