If ns has 2 dimensions, average first along last dimension.

Parameters:

nsnumpy.ndarray

A 1- or 2- D array that contains the value of the nodes.

atlasstr, os.PathLike, 3D Nifti1Image, or numpy.ndarray

The 3d nifti image of an atlas, a string or path to its position, or a list of coordinates of the center of mass of parcels.
