Question about REM density #175

Open laura-hainke opened 5 months ago

laura-hainke commented 5 months ago

Hello, how is rapid eye movement density calculated with YASA? After using rem_detect() and summary(), the parameter "Density" is shown, but what is the unit? Thank you!

The density parameter is the number of events per minute:

Thanks, Raphael

Probably worth adding this quickly to the documentation before closing the issue. (I'll do it.)
