[Neuroimaging] [DIPY] propagator anisotropy estimation using MAP(L)MRI

[Rutger Fick]

Hi Ping,

Great to hear you're trying the toolbox!

Thanks for pointing out the bug, I just fixed it in the repository, so you
should be able to load the gradient directions without having the error now.

Dmipy is completely general in that it can import any PGSE-based
acquisition scheme with any number of non-diffusion weighted volumes. Dmipy
internally normalizes the signal according to the mean of all b0-values,
and automatically detects which measurements belong to the same acquisition
shell.

Let me know if you have any more questions or just generally what your
experience is using dmipy :-)

Best,
Rutger
