Channel order T1gd,T1w,T2w,FLAIR is exactly the recorded MLX order; case.input_sha256 contains each recorded role's checksum. Original model.pt was found in the recorded HF snapshot 370f7f9d062745fbac445e7fe6d6616d35df04ec and matches source_sha256. Sigmoid, inverse transform, threshold 0.5 and original BraTS label precedence 4 > 1 > 2 used. Dice covers every label including background; all MRI grids and both mask affines/shapes match. AMP is disabled for CPU float32 inference. Raw outputs, source configuration, dependency versions and log: work/reference/segresnet-brats/. Training-exposed MSD case; this is reproducibility evidence, not an accuracy study.", |
