Hi Juke - You can convert path.pd.nii.gz to a probability by normalizing it to a sum of 1. The numbers in there are the number of occurrences of the path in any specific voxel, among the 1000 or so paths that are sampled by the MCMC algorithm.
Hope this helps, a.y > Dear Dr. Yendiki and TRACULA experts, > > I was wondering what the unit of posterior distributions of reconstructed > paths?
