The code I am using for i.e. switch on the red slice view is: current\_slice\_node = slicer.mrmlScene.GetNodeByID(‘vtkMRMLModelDisplayNode1’) current\_slice\_node.VisibilityOn() This code works well until one changes the position of the slice by i.e. scrolling in the slice view. I guess since the “eye” in the slice view is still “closed” the update will set the visibility again to 0 and…
