Type Definition for the Custom Parcellation Approach.

A TypedDict representing the subkeys (second level keys for “Custom”) for the user-defined Custom parcellation approach. The structure is as follows:

{
    "maps": "path/to/parcellation.nii.gz",
    "nodes": ["LH_Vis1", "LH_Vis2", "LH_Hippocampus", "RH_Vis1", "RH_Vis2", "RH_Vis3", "RH_Hippocampus"],
    "regions": {
        "Visual": CustomRegionHemispheres
        "Hippocampus": CustomRegionHemispheres
    }
}

Added in version 0.23.6.

Parameters:

• maps (str) – Path to the Custom parcellation.

• nodes (list[str]) – List of nodes (ROIs) in the Custom parcellation. Ordered in ascending order of their label ID in the parcellation and must exclude “Background”.

• regions (dict[str, CustomRegionHemispheres]) – Dictionary mapping the regions to their left and right hemispheres.
