Bvec and bval files available for human diffusion MRI?

Hi there,

I would like to run a tractography analysis on the highresolution diffusion MRI data from the BrainSpan Reference Atlas, specifically the 34 yrs human data due to the rare combination of with the Parvalbumin sections.

However, I was not able to find the b-value and gradient information, i.e., the bval and bvec files, which are necessary for tractography. The documentation doesn’t mention them either. Are these files still available somewhere?

Many thanks,

Aslan Abivardi
