Dear Administrator， I have successfully signed up for the competition. May I ask why I still cannot obtain the data set?

Hi @msadi002, Thank you for your feedback, and sorry for the late reply. The METs testing cases include both native space and Atlas space volumes. I will check the mentioned case and will write back here. Best regards, /Mehdi
Hi @vchung Could you please look into this : BraTS-MET-01094-002.nii.gz. Found these unexpected values (they should not be there) [np.uint16(6)] Thank you
Good Morning Regarding the BraTS 2026 Brain Metastases Challenge: Given that the training dataset is provided in native space, can you clarify whether the test dataset will also be in native space or registered to SRI24 space? This will help us determine whether our models need to handle native space data or should be designed for SRI24-registered inputs.
Hi @Y.HANHAN, Accessing the data for this challenge requires some extra steps: 1. Complete the [Data Access form](https://forms.gle/UiCpXos2zKFPdMnK6).
