And I got my bval and bvec from running dicom2nii. How come it does not match my data?

Hi Khoi,

Thanks so much for replying.

So I attached my bval and bvec with this email and I noticed my bval start from 0 and then 800,...

How do I fix this and have DTIFIT to run so that I can continue my analysis?

Thanks.

Hi,

The volume counter in FSLeyes starts at 0. Hence, if your last volume number is 33, probably that the data has 34 volumes.

best,
Khoi
