Note that tracula doesn't extract from the atlas the exact spatial location of the tracts. It only extracts which anatomical labels are the neighbors of the tract at each point along its trajectory. So it's not as sensitive to misregistration as a voxel-based analysis would be. Our paper discusses all this:

Hi, I would like to know if for a probabilistic tractrography using TRACULA I can use the CVS space as a common template to register the diffusion data instead of MNI template. How I should change for the CVS space the following: set doregmni = 1 which is the default for the MNI space. If I want to use bo th MNI template and CVS template for comparison purposes how this can be don e? THANKS. Antonella
