What are the attributes that SlicerRT expects for a dose node to have? I can’t find a description of these.

Basically I want to be able to use my own produced dose matrix into SlicerRT.

These two attributes in the parent study item:

If you move the volume under a study that is under a patient, and choose Convert into dose volume in the right-click menu, then you can do it from the UI. Otherwise you need to set it up yourself.

So, the dose nodes must be inside a study and this study is the one that needs to have these attributes?

Is not important to have the modality as `RTDOSE` then?

Exactly. The DICOM attributes in SH are populated when importing from DICOM, and when exporting to DICOM, for easier identification, but are not used in this case.
