Dear FSL Users:
I was wondering if anyone knows how to get actual radial diffusivity values in TBSS. I have followed
the tutorial for "Using non-FA Images in TBSS" using a scaling factor of 2000000 and end up with
RD values ranging from -1500 to 4000. First, I don't understand why there are negative eigenvalues
and second, how to scale to the actual RD in (micrometers squared)/msec.
Any help would be most appreciated!!
Sincerely,
Marc
