Dear BraTS-METS Organizing Team, We are a team of three final-year Computer Engineering students working on a supervised, non-commercial graduation project on brain metastasis segmentation using deep learning. We would like to request access to the labeled BraTS-METS training MRI data and expert ground-truth segmentation masks, particularly the Yale-contributed cases from BraTS-METS 2023. The 2023 MET folder now contains only a README stating that the data have been moved or archived. The 2026 challenge is closed, no registration option is available, and the Files page shows only a schedule and a PNG file. Could you please advise how new researchers can obtain access after challenge closure, or provide the current official repository or application procedure? We already have Pretreat-MetsToBrain-Masks. If available, we would also appreciate case-source or overlap information to avoid including the same patients in training and evaluation across datasets. We are requesting only publicly releasable training images and labels, not withheld test data or validation ground-truth labels. We will comply with the applicable data-use terms and citation requirements. Thank you for your guidance. Best regards, Zeynep Azra Kabadayı
