I'm trying to generate Presentation State for an image.
I tried this tutorial : https://github.com/EnvoyAI/examples/tree/master/test-gsps
I generated the ".pre" file but couldn't open it with Weasis or Osirix.

Do you have any dicom files with some GSPS examples to try them out?
Should i try a different viewer?

Here is the link to the dicom file : https://usaupload.com/4Xtu/test.dcm
Here is the link to the ".pre" file: https://usaupload.com/4Xtt/image.pre

The pre file looks like this:
