Hi Celine - Since 5.2, there are 2 types of measures in the pathstats.byvoxel.txt file: The value at every point along the trajectory sampled at roughly the center of the bundle, or the value at every point along the trajectory averaged over the width of the bundle. Sorry, there are no other measures available at this point. If I understand correctly, you would like to see something like a profile of the measure of interest at every point along the trajectory?

Hi Tracula team I am using tracula to study the corticospinal tract in a patient population. I am wondering if there would be a way to have the different DTI metrics from the whole tract at different depth/portion of the tracts. Something like the information given by the pathstats.byvoxel.txt file, but for the whole width of the tract? If not, do you see a way to sample the value of the diffusion metrics on a certain tract starting from the cortex (like with projfrac or projdist with the WM surface)? Thanks very much for your help Celine
