[Mrtrix-discussion] How to get the components of gradient direction for Philips PAR/REC scans

[Luis Concha]

In PAR/REC version 4.2, this is in one of the columns after the tag
===IMAGE INFORMATION===. The header of that huge table will tell you which
column tells you the information (diffusion (ap, fh, rl)) and is a
three-float number. Similarly, the b value is in the column labelled diff..
