Zeiss Xradia 520 metadata extraction


I have been given a Zeiss XRadia TXRM file but as I do not have regular access to a XRadia machine and its data processing software. I have succeeded in extracting the image files using the XRM reader created by mrsutherland (https://github.com/mrsutherland/XRM_Reader) but have not been able to get any metadata from it.

So, can anyone here suggest a means by which I can extract the metadata? It is holidays here and the provider of the data is not available.
