Table 4 The p-value of Wilcoxon two-sample tests between outer (rostrum, genu, and splenium) and inner (rostral body, anterior and posterior mid-body, and isthmus) subdivisions of corpus callosum

  1. The outer subdivisions have significantly lower average Dice measures than the inner subdivision for all azimuth and elevation rotation angles (p-values less than 0.0004). For skew angles, however, the outer subdivisions do not show significantly lower average Dice measures than the inner subdivision (5 out of 6 p-values are more than 0.01). See Table 3 for the means and standard deviations of the 11 subjects.
