Dear BraTS Organizing Committee, My name is Dogukan Parlak, a 4th-year Computer Engineering student at Aydin Adnan Menderes University, Turkey. I am working on my undergraduate thesis on deep learning-based brain tumor segmentation under the supervision of my thesis advisor. I would like to request access to the most recent version of the BraTS training data available for research use. My main interest is the adult glioma data, including the BraTS 2025 pre- and post-treatment glioma dataset (BraTS-GLI) and any updated or quality-controlled versions released with BraTS 2026 (e.g., the adult glioma data used in BraTS-GoAT). Access to the BraTS 2026 brain metastases (BraTS-METS) data would also be very helpful. I understand that registration for the 2025 and 2026 challenges has closed, and I would be grateful if access could be granted to my Synapse account for academic research purposes. I confirm that: - The data will be used solely for non-commercial academic research (thesis), - I will comply with the CC BY-NC license and the BraTS data usage terms, - I will cite the flagship BraTS manuscript and the task-specific publications in my thesis and any related publication, - I will not redistribute the data. If the data is going to be released through TCIA instead, I would appreciate any information on the expected timeline. Thank you for your time and for making this valuable resource available to the research community. Best regards, Dogukan Parlak Computer Engineering, Aydin Adnan Menderes University
