Interhemispheric registration of fsaverage surfaces to a left–right hybrid target using Landmark-SBR. (A) Fsaverage midthickness surfaces can be jointly visualized in Caret to demonstrate the lack of geographic correspondence. The left and right hemisphere meshes are specified as 164k_fs_L and 164k_fs_R, respectively. (B) Fifty-five landmark contours identified along corresponding geographic locations in the left and right hemisphere fsaverage surfaces. (C) Landmarks projected to the left and right spherical standard surfaces. (D) Hybrid landmarks generated by averaging the right and mirror-flipped left spherical landmarks. (E) Geographic correspondences of the resampled fsaverage midthickness and inflated surfaces on the hybrid 164k_fs_LR mesh.
