Represents the maximal mapping from nodes to voxels. ‘maximal’, in this context, means that to each node all voxels are associated that are contained in lines connecting white and grey matter.
Each voxel can be associated with multiple nodes.
Parameters: | volgeom: volgeom.VolGeom :
white: surf.Surface :
pial: surf.Surface :
intermediate: surf.Surface (default: None). :
nsteps: int (default: 10) :
start_fr: float (default: 0) :
stop_fr: float (default: 1) :
start_mm: float (default: 0) :
stop_mm: float (default: 0) :

Notes
‘pial’ and ‘white’ should have the same topology.
