Hi,

Is there a way to run these commands in PythonSlicer?

I need to access `mrmlScene` from PythonSlicer, but I’m not sure how to do it. Any suggestions?

PythonSlicer exposes only the python part, not the slicer application part. You can use the `--no-main-window` to run a script with app features but no gui.
