I am trying to receive some data via OpenIGTLink with additional data added. For example I can already receive a vtkMRMLScalarVolumeNode but in this node I cannot include information about the patient (e.g. UID). In the overview page of OpenIGTLinkIF I found some information that BindMessages could solve the problem (https://www.slicer.org/wiki/Documentation/Nightly/Developers/OpenIGTLinkIF).
Unfortunately I have not found further information on how to use it and in the source files of the project I also hardly found any hints. Are BindMessages support via the Python-Interface at all?
Anyone has a small example on how to use them?
