When we use effect.setParameter(“Minimum Threshold”, 265) and then:

print(slicer.mrmlScene.GetFirstNodeByClass(“vtkMRMLSegmentEditorNode”))

It says that the parameter is still set at the default of 115 (Local Threshold.MinimumThreshold:115)

Are we missing a line of code @lassoan?

We have figured it out. Thanks!

The solution is you write `effect.setParameter("MinimumThreshold", "265")` - no SPACE
