7.10.3. nilearn.plotting.find_parcellation_cut_coords

nilearn.plotting.find_parcellation_cut_coords(labels_img, background_label=0, return_label_names=False, label_hemisphere='left')

Return coordinates of center of mass of 3D parcellation atlas

Parameters:

labels_img: 3D Nifti1Image

A brain parcellation atlas with specific mask labels for each parcellated region.

background_label: int, optional (default 0)

Label value used in labels_img to represent background.

return_label_names: bool, optional (default False)

Returns list of labels

label_hemisphere: ‘left’ or ‘right’, optional (default ‘left’)

Choice of hemisphere to compute label center coords for. Applies only in cases where atlas labels are lateralized. Eg. Yeo or Harvard Oxford atlas.

Returns:

coords: numpy.ndarray of shape (n_labels, 3)

Label regions cut coordinates in image space (mm).

labels_list: list, optional

Label region. Returned only when return_label_names is True.
