Hello, 

I have tried to process this MRI a few times now and it always seems to get stuck on the step I have pasted below here. I have tried to fix the defect myself by editing the voxels manually, but that has also not seemed to help. I've looked through the MRI and there are no obvious deformities/defects. Any help with the next steps would be much appreciated. 

Best,
Salil
