Shape variability expressed in terms of mean distances (MD) between the shapes or Hausdorff distances (HD). The largest values are obtained for large structures like cortex (HD: 0.77 mm, MD: 0.11 mm), thalamus, and some white matter tracts like corpus callosum, optic tract, and anterior commissure, while the smallest values are obtained for the latero-dorsal thalamic nuclei (LD) (HD: 0.04 mm, MD: 0.02 mm).
