Nifti files don't store that info. You'd have to get the gradient table and
b-values either from the dicom header or from the scanner.

Gotcha. I was wondering if it would be possible to extract the bvecs and bval
files directly from the Nifti file, however, it seems like based on the
documentation that this is not possible and I will have to specify the bvals
and bvecs and make sure they are formatted correctly for TRACULA.
Thanks for the reply!

Hello I was given a dataset already in Nifti format that I would like to run
Tracula on. Is it possible to input Nifti files in the config file instead of
DICOMs? How would this work?
Best,
Daniel Callow
