DICOM data contains the information needed to produce bvecs and bvals, but
NIFTI files do not. You would need to receive the gradient table and
bvalues separately.

Subject: [FSL] 3d nii to 4d with bvec and bval
Dear FSL experts,
I have been previously using mricron for conversion of dicom images to nii
format with bvec and bvalue to be used in TBSS. The current problem is that
I have received 3d nii format of DWIs. There is "fslmerge" to convert 3d to
4d files, but with this command I won't receive bvec and bval files. Mricron
also comes short when the input is a 3d nii. Could you please give me a clue
of how to convert 3d nii to 4d files with bvec and bval?
Any suggestion is gratefully appreciated.
Regards,
Arman
