The error occurred because the images do not all have same orientation and/or
voxel sizes. Some of them have voxel-to-world mappings of [-2 0 0 77.2; 0 2
0 -107.6; 0 0 4 -53.4] and others have mappings of [-2 0 0 78.1; 0 2 0
-118.7; 0 0 4 -55.2]. It would appear that they may not all be resliced to
the same space.
