Is it a feature or a bug that slicer.util.getFirstNodeByName() returns None when parentheses are in the name of a node?
I don’t know if this is intended, but I think it’s because the name is being treated as a regular expression. A workaround is to escape the parentheses by preceding them with a backslash \
.
For the possible cause:
Another workaround is to call vtkMRMLScene::GetFirstNode
yourself:
slicer.mrmlScene.GetFirstNode(your_node_name, None, False, True)```
