Hi,
Thanks Matt.

In your method described, probtrackx needs many RAM because of reading merged_th, ph, f .
Do you have plan that probtrackx allows single mask to parallelize tracking in order to speed up processing ?
i.e. probtrackx splits number of seed voxels into number of threads and tracks from divided seeds independently.
Thanks
Kenji
