Hello folks :) Thank you in advance!
I'm getting this cryptic error:
Loading Open-Ephys: reading settings...

It probably can't find the '@recordEngine' key because your data may be older than the versions supported by pyopenephys and that key was not included in the settings at the time. Try deleting the [@recordEngine] brakets or just directly indicate the openephys format you are using, e.g. self.format='openephys'
