Interesting; I didn't know that was possible!

What leads you to conclude they "don't seem open"?

I don't have any inside info that they are interested. But they did add the sleep staging data based on input from people like me, and they have solicited requests for more data export.

I was actually more interested in spo2 data, though, which they also should be able to export.

For browsing edf files, I can recommend the EDFbrowser: https://www.teuniz.net/edfbrowser/

The basic format description is at http://www.edfplus.info/

As far as I know they have not changed the sleep state format since before DREEM-2 first came out, it's still [WAKE WAKE WAKE etc etc] stored as a really long text string. Before I figured out how to change their format to the ZEO integer style they did convert a month's worth my data to integers  but said it was a one-time thing and I couldn't ask for it again.  When I signed up for the research program I asked if I would be able to get spO2 info in the raw data but they said that since both the regular and IR pulse sensors were located in the scalp area it was't going to be possible to get reliables spO2 info from them.  Fingertip or earlobe gadgets remain the best source for  spO2.

Ah, OK; good to know.

Note, in case this wasn't already clear: pre-release OSCAR code (available via the gitlab master repo) will import Dreem hypogram data from their CSV export; no longer any need to convert it.

I'm not sure if they've publicly released any of the pre-releases. I build it from the gitlab source code.
