Atlas

An atlas provides a guide to the location of anatomical features in a coordinate space.

—[1] p. 55

An atlas provides a defined coordinate space, a template for aligning images, and labels for regions of interest.

Currently C-PAC only supports atlases in NifTI format.

CIFTI is a popular atlas format not yet supported by C-PAC. As always, if anyone wants to share any tips or hacks with us, we are an open-source platform after all. Below are some resources that might help enable CIFTI atlas support in a future version of C-PAC.
