Voxel-wise statistics.

<p>Mean FA skeleton for each registration approach: green (T, standard template), blue (GM, group mean), light blue (GW, group-wise atlas) and black (N, most representative subject) overlaid onto the MNI152 standard template for anatomical orientation. Clusters of voxels of significantly decreased FA values of POAG patients compared to controls are marked red (p<0.05, corrected for multiple comparisons). *Coordinate in MNI_152 space.
