Hello!

I am trying to automate a data extraction process from a medical device using python, however I’m having issue extracing the data from a ImageMetaList node after receiving it as a response. Is there a way I’m supposed to be able to make an ImageMetaElement such that I can use GetImageMetaElement(), or is there another way I’m missing?

Any advice would be appreciated!

My overall goal is to not have to interact with the Widgets GUI at all, and just query data and place them into nodes for Slicer which I can then use, using python only.

Also wanted to mention that WriteXML is not reachable from the python object, so I can’t use that either to extract the data.

Forgot to clarify, I am using Slicer 5.6.2, and the ImageMetaList I am referring to is from SlicerOpenIGTLink [here](https://github.com/openigtlink/SlicerOpenIGTLink/blob/master/OpenIGTLinkIF/MRML/vtkMRMLImageMetaListNode.cxx)
