General API for fetching, identifying, and defining atlas nodes based on coordinates and/or labels.
Parameters
----------
atlas : str
Name of a Nilearn-hosted coordinate or parcellation/label-based atlas supported for fetching.
See Nilearn's datasets.atlas module for more detailed reference.
uatlas : str
File path to atlas parcellation Nifti1Image in MNI template space.
ref_txt : str
Path to an atlas reference .txt file that maps labels to intensities corresponding to uatlas.
parc : bool
Indicates whether to use parcels instead of coordinates as ROI nodes.
in_file : str
File path to Nifti1Image object whose affine will provide sampling reference for fetching.
use_AAL_naming : bool
Indicates whether to perform Automated-Anatomical Labeling of each coordinate from a list of a voxel
coordinates.
clustering : bool
Indicates whether clustering was performed. Default is False.
Returns
-------
labels : list
List of string labels corresponding to ROI nodes.
coords : list
List of (x, y, z) tuples in mm-space corresponding to a coordinate atlas used or
which represent the center-of-mass of each parcellation node.
atlas : str
Name of atlas parcellation (can differ slightly from fetch API string).
networks_list : list
List of RSN's and their associated cooordinates, if predefined uniquely for a given atlas.
parcel_list : list
List of 3D boolean numpy arrays or binarized Nifti1Images corresponding to ROI masks.
par_max : int
The maximum label intensity in the parcellation image.
uatlas : str
File path to atlas parcellation Nifti1Image in MNI template space.
dir_path : str
Path to directory containing subject derivative data for given run.
