Dear BraTS 2025 Organizing Team and Community, I hope this message finds you well. I have been actively working on my submission for the BraTS 2025 Task 6 (Pre-Treatment Pediatric Tumors) and have dedicated several months to developing and testing my Docker image. However, I am currently facing unforeseen technical issues with the build process, which have prevented me from successfully uploading my final Docker image to the Synapse system before the deadline, now less than four hours away. Despite my efforts to resolve these challenges, including issues with dependency installations and model downloads, I have been unable to complete the submission in time. I kindly request a one- or two-day extension to allow me to address these technical difficulties, finalize my Docker image, and ensure a proper submission. This additional time would help me avoid wasting the significant effort invested over the past months and ensure the integrity of my work is fairly evaluated. I apologize for any inconvenience this may cause and greatly appreciate your understanding. Please let me know if any additional information or documentation is needed to support this request. Thank you for considering my situation, and I look forward to your response. Best regards, Amin Tavallaii
