Usage - align your own maps across species

The folder deformation_macaque-human contains spherical deformation files necessary for align your data Connectome Workbench is required.

Note: This is topological contrained surface alignment. The original spherical alignment was created using MSM on 10k resolution surfaces.

• surfaces folder contains the surface files for human and macaque. The human surface data need to be on the standard surface spaces - 32k_fs_LR or 10k_fs_LR resolution. The macaque surface data need to be on MacaqueYerkes19 surface space - 32k_fs_LR or 10k_fs_LR resolution.

• workbench command: -metric-resample, -cifti-resample, -label-resample

• Macaque (32k_fs_LR) to human:
