Hi Levi,

try to include the inverse transformation matrix (typically, diff2standard) using --invxfm and the seed reference image using --seedref (the standard template volume that you have coregistered your diffusion data to) in the terminal command you have just sent me.


Cheers,
Matteo

Hi Levi,

Can you please copy the probtrackx.log file that you should have, so that I can check the probtrackx command that you have used?


Cheers,
Matteo
