I want to test my new reconstruction method in SD_Stream tractography. However, only fod can be used in SD_Stream. I have to move my fod from Matlab to Mrtrix tools, steps are as follows.
the dirorder command is used to chage cartesian coordinates direction (642 directions) [x y z] to “[az el]”.
Next, I use amp2sh command with new “[az el]” directions convert my fod files to spherical harmonic coefficient.
Finally, using mrview to check my result.
However, the FOD in mrview isn’t show right directions, and I don’t know what I did wrong.
Thank you for your time.
