Vertex areas are used in resampling from the native mesh to the 32k
registered mesh (this process occurs on the sphere and aside from the
vertex areas which are calculated on the subjects native mesh and 32k
registered mesh midthicknesses the midthicknesses are not involved).
The small amount of
Let me try to clear up some confusion:
To answer the original question, the area correction that the minimal
preprocessing pipelines paper refers to for smoothing and resampling
surface data makes use of the individual's midthickness surface, not a
group average, for the reasons I previously
