Hello,

We are analysing the Stanford EDFs from the STAGES dataset. The EDFs were recorded using the SOMNOmedics data collection system.

The body position (BPos) channel appears to take on 5 discrete values. Our best guess is: 117.7 (supine), 78.44 (left or right), 50.98 (left or right), 23.53 (upright), 0.004608 (prone).

Could someone please confirm whether this is correct or not?

Thank you, have a great day!

Thanks for using the site. I'll reach out to our STAGES contact to see if we can get more information on the position channel.

I heard back, unfortunately the position signal encoding information was not retained by the STAGES data contributor, so we can't be certain of the different position signal value meanings across the STAGES sites.
