Different nonlinear warpage types applied to 5 different subjects (only one subject is shown for each warpage type—MNI152 T1 2 mm with 91 × 109 × 91 voxels): (A) an original subject; (B) differential rotation with the amount of rotation proportional to the distance from the center in the axial plane (whirl); (C) differential stretch in the anterior direction; (D) differential rotation with the amount of rotation proportional to the distance from the axial plane in the longitudinal direction (twist); (E) nonuniform compression in the axial plane proportional to the the longitudinal distance; (F) nonuniform compression in the longitudinal direction relative to the position in the axial plane
