Hello everyone ,
I just want to got radial diffusivity from L2,L3 images .I found the following two methods in email lists :
1. fslmerge -t dti_L23 dti_L2 dti_L3
fslmaths dti_L23 -Tmean Radial_D
2. fslmaths dti_L2 -add dti_L3 dti_L23
fslmaths dti_L23 -div 2 Radial_D
I don't know which one is better ,or say there is more better method to caculate radial diffusivity .
Please tell me .
Mand thands.
Xin-Fa Shi .
