I'm processing some Prisma data and noticed heudiconv isn't outputing bvals or bvecs. When I run the conversion using command-line dcm2niix, the bvals/bvecs were successfully made.

I thought this was a problem with nipype's dcm2nii.py interface - but even after making these changes I was still unable to produce them. Any ideas as to what is causing this?

For reference, here is dcm2niix's stdout for my diffusion scans
