Hi all,
I'm running TBSS analysis on non-FA data: namely, AD, MD and RD values. As you know, the minimum and maximum intensity values need to be checked before running the 'tbss_preproc' script by entering the command 'fslstats ____.nii.gz -R'.
However, I'm getting strange intensity values for some subjects... For example, one subject happens to have
an RD intensity range of 0 - 4803.45. This doesn't seem normal - I would expect this (based on my Explore-DTI tractography results) to be more in the range of 0 - 0.0005.
Just wondering if anyone could shed light on this: am I correct to assume that my range should be in decimals, not thousands? My FA data, however, is in the normal intensity range of 0:1.
Many thanks,
Sinéad
