Hi all, I have a series of volumetric GM masks that I used to calculate a functional connectivity matrix. Now I want to use the same masks to calculate a structural connectivity matrix (number of streamlines). I registered all masks in diffusion space for all subjects. My idea was to use probtrackx2 with a matrix option (and list of waypoints), but I am really unsure about which options I have to use: --omatrix1 and then sum all voxels of the mask or --omatrix3?
Could you help me in writing my script? Thank you for any help
