Hi, the first thing to check is that the 2 input images are both
brain-extracted, both of the same image dimensions and well-aligned
to each other.
If this is all correct then the most likely issue is that you are
running out of RAM/swap/process-size. You could try cutting out un-
necessary slices (if any) in x, y or z, or moving to a 64-bit machine?
Hope this helps - Cheers, Steve.
