export the hypnogram files from PSG TWin software

[mahmoodping]

Hi

I am working on a project to predict OSA from PSG studies.

I have PSG TWin 4.5.2 installed and I have PSG files in edf format that belong to the patients.

my question is how can I get the Hypnogram files which contain annotations in edf+ format

Briefly, I wish my dataset to be like this dataset:
https://physionet.org/content/sleep-edfx/1.0.0/

any help?

Thanks in advance
