I am loading a DICOM dataset from a proton therapy treatment plan from a RaySearch TPS. This inclused the DICOM-CT, DICOM-RTDOSE, DICOM-RTPLAN and DICOM-STRUCT files, However I have problems with the beam data and receive the following error (underneath).  
Could it be that this type of plan is not supported?

Regards
