Thanks for the clarification.

I have succeeded in installing the extensions using yesterday’s preview release version. But I still have two other questions.

1. I want to export deformable transform, but when I install “SlicerRT” extension, “DICOM Registration Export” module didn’t show up. I have followed this [thread](https://discourse.slicer.org/t/import-of-registration-dicom-files/368/22) but don’t know how to use that? Could you give some advice?

2. I was a bit confused about the warning(?) in Python Interactor (shown below). I have installed “SlicerRT” extension and also succeeded in importing RT structure, but the warning(?) still existed? Does it make any difference?

Thank you!
