Dear Mrtrix Team,

I have a question concerning the relationship of estimated orientation 1 and 2 (peak1 and peak2). I would like to compare the peaks of different measurements (various b-values etc.).

I already registered all directions to one template. But when I want to consult areas where both proportion of orientation are almost the same I have the problem that I don’t know how I can compare the directions correctly because how can I be sure that peak 1 of measurement 1 is not equivalent to peak 2 of measurement 2?

So my questions are:

- Is there a function which resort my orientations hence I can carefully compare orientations per voxel from different measurements? So that in the end all peak1 are corresponding to peak 1.

Thank you

Best

Max
