I am interested in performing surface-based probabilistic tracking to every other brain voxel. Do I need to create a separate target mask volume for every voxel (~15k for the down-sampled resolution I am aiming to use) ? Or is there a way to have probtrackx accept a single mask, split it up by voxel automatically, and still provide a matrix_seeds_to_all_targets files of nVertices x nBrainVoxels?
Cheer,
Ryan
