Outputted diffusion bval are not the effective b-values anymore

[jeremie-fouquet]

Describe the bug
Since commit de6cb1e, the bvals are read from PVM_DwBvalEach instead of PVM_DwEffBval. This has two effects

1. The outputted .bval file contains the requested bval instead of the effective bvals. I would argue the effective values are much more useful.
2. By default, the bvals do not hold the b0 values anymore. The way this was handled led to the ordering problem described in issue Ordering of BVAL/BVEC in DTI data #90.

Suggested solution
I'd suggest going back to getting the bval from PVM_DwEffBval. It would solve both points mentioned above. @dvm-shlee, do you agree?

@jeremie-fouquet,

I have a question about the effective bvals and manipulating them for Bruker systems. Do you have an email address I can send my question to as it is not directly relevant to brkraw?

Thanks

[jeremie-fouquet]

Yes, sure.
