Hi to everyone. Today I’m trying to change the SubjectHierarchy name using Python code. My goal is the next one:

Actual name: VAL22^Val22(AW388…

Thanks for your help @cpinter. We are not very familiarized with this type of code. Could you explain a little bit more about what is dataNode?

A simple example of the implementation could help us more. 🙂

The first link I provided contains the actual implementation.

The documentation of Slicer is quite extensive, and you can learn about the basics very quickly. For example, you can find out what is a node here:
