Dwi2tensor output is empty


#1

Hi All,

I have preprocessed the DWI data and applied dwi2tensor to get a tensor image, but I had an empty tensor image (dwi2tensor dwi -fslgrad bvecs bvals dt). However, I got the tensor image when I used dtifit in FSL. Does anyone have any idea about it? And I didn’t get any error during dwi2tensor processing.

Thanks,
Gzds

That’s unexpected. What does mrstats dt.mif report? Could it be an issue with the brightness/contrast in the display…? What values do you see for the intensity range in the View tool?
