Hello David,
you can find the source code for the vesselness Slicer plugin here
https://github.com/haehn/VMTKSlicerExtension/blob/master/PythonModules/SlicerVmtkCommonLib/VesselnessFilteringLogic.py
I see that method for generating the steps is kept as the default (for the C++
class), which is "logarithmic", while vmtk default is "equispaced".
Try to specify
-stepmethod logarithmic
in the vmtk command line and see what happens.
Best,
Luca
