Dear 3D Slicer support,

How to remove transformed node from the active transformed list via python script?

There is a great tutorial on how to set and observe transformation:  
[https://slicer.readthedocs.io/en/latest/developer\_guide/script\_repository.html?highlight=transform#apply-a-transform-to-a-transformable-node](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html?highlight=transform#apply-a-transform-to-a-transformable-node)

however I could not find an opposing similar solution for removal

Thank you, Edgaras

I have found the solution:  
transformableNode.SetAndObserveTransformNodeID(None)
