Table of weight map values generated for the right hemisphere FA map defined in terms of ICBM-DTI-81 atlas regions. Includes the percent contribution and total voxels for each region. Note that the voxels included from the Body of the corpus callosum were excluded in the final analysis to test the contribution to classification of the region identified in the univariate contrast.
