[Mrtrix-discussion] b-value correction

[Donald Tournier]

Good to know that the -nosearch option doesn't prevent rotations, I was
getting worried about it. As to the blurring in the FA maps, I'm talking
about a much greater effect than interpolation alone, and the
misregistration is clear when cycling through the DW images. Should only
affect high b-value and/or low SNR images though.

Thanks for the feedback!

Cheers,
Donald.
