thanks for nice answer, but I have one more quetion.
While I used 3dDWItoDT command, it produce FA and MD, and I also made RD from L2 and L3 data
however, MD and RD value is higher than about 100 - 1000
Many paper showed that MD and RD values are not much than 1
How can I calculate the raw values of MD and RD to modified(?) values which are not exceed 1
Could you give some advice?
All the best
leetaey.
