Hi, If you want to do this outside of FSLView, then use atlasquery (see online documentation).

Is there a command option to get the all the 4 probability values for each of the fibers separately for a particular voxel in the MNI co-ordinate system? the purpose is that i would like to mutually exclude Anterior thalamic radiation and Uncinate fasciculus based on these probability values. > > Regards > Jay
