Hi Joe,
I can't test it right away, but it looks to me like you're missing a step in
which you clip the surface into branches according to the extracted centerline
branches:
vmtksurfacereader
-ifile neurosurgery/RICA_Pt001_1010rev.vtp
--pipe vmtkbranchextractor
-ifile neurosurgery/RICA_Pt001_centerline_smooth.vtp
-radiusarray@ MaximumInscribedSphereRadius
--pipe vmtkbranchclipper
--pipe vmtkbifurcationsections
-distancespheres 5
-ofile neurosurgery/bifurcationsections.dat
--pipe vmtkbranchsections
-ofile neurosurgery/branchsections.dat
Note that using
-radiusarray@ MaximumInscribedSphereRadius
I'm forcing radiusarray to be pushed through the pipe, so you don't need to
specify it for the subsequent scripts.
Hope I nailed it.
Best regards
Luca
