It is possible that it is all there but that the display scale is set such that it looks black.

I ran BET, then Eddy current, then DTIFIT. The previous steps were okay, but I had a problem with this step (DTIFIT). I got no error messages everything ran smoothly which is why i don't know what hints to give. Can someone help please? Dave
