Represents the minimal mapping from nodes to voxels. ‘minimal’, in this context, means that the mapping from voxels to nodes is many-to-one (i.e. each voxel is associated with at most one node)
Each voxel can be associated with just a single node.
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.
Methods
