The ten most discriminating parameters, according to the Fisher (F-) coefficient and their corresponding Wilcoxon test p-values are calculated between segments of the corpus callosum for both patients and controls.

SumAverg, sum average; Sum Varnc, sum variance, SumEntrp, sum entropy; DiffVarnc, difference variance, SumOfSqs, sum of squares; WavEnLH, energy of wavelet coefficients in subband LH; WavEnLL, energy of wavelet coefficients in subband LL.

* p-values of under 0.05 are considered statistically significant
