@BraTS2026Participants Dear Participants of Task 4 (Inpainting), some of you have contacted us regarding the leaderboard, asking whether it will be reopened. For the moment is remains closed, I will post an update if there are any changes. **However, please note that you can locally validate your models yourself. You can use the PyPI package 'inpainting', installable via pip. The link is the following: https://pypi.org/project/inpainting/** **You find a function called generate_metrics() there, which is exactly what is used for the leaderboard.** This function can provide additional metrics, which are not displayed on the leaderboard. There is documentation on PyPI as well as on GitHub. **Please note that generate_metrics() takes four inputs, including the original voided T1 image. **This is required for normalization. If this input is not passed, the function can yield invalid results. Please feel free to use this package to locally validate your models - it is very easy to use! Don't hesitate to reach out to use if you have any questions! Best Paula
