For the whole competition i have been thinking that <275mm3 lesions will only be evaluated on Detection metrics as previously there was something written like, 'We will apply the segmentation evaluation metrics only for lesions larger than 275 mm3', now i checked and was shocked to see the segmentation threshold got changed to 27mm3. So please someone confirm once if all lesions >27mm3 are evaluated for segmentation? Also i want to ask about final leaderboard, do both the segmentation and detection of half of the competition weigh equally or all the metrics DSC, NSD and F1 are weighted equally which would make the final leaderboard heavier for segmentation category, so I would request organisers to confirm this?

Dear @vineet3jangir I am sorry for this confusion. I confirm that the volume threshold is 27 mm**3, so all the lesions (subregion) under this threshold will be evaluated via detection metrics; the larger ones will be used for segmentation metrics. You can follow it via the official [BraTS evaluation](https://github.com/BraTS/BraTS_evaluation/tree/main). Regarding the weight between the segmentation and detection metrics, we will announce it by the end of the upcoming week. Best regards, /Mehdi
