Dear FSLer,
I have a problem with DFT there is no voxels generated in FA image after using DFT.
My processing procedure was merging original 26 NIFITI files to one 4D dti data, then eddy correct was applied and BET was used to generated a binary mask. I created bvals and bvecs using dtiRawBuildBvecs.m from standford https://github.com/vistalab/vistasoft/blob/master/mrDiffusion/preprocess/dtiRawBuildBvecs.m#L40-L44 as gradient directions was presented in dwepi.grads files by our GE scanner.
Finally, there was no voxels generated in FA image when I checked DTIFIT results. Fslview showed black everywhere. Does anyone know what is going on here? Any suggestions would be grateful!
Best Wishes,
Joyce
