That helped a lot! Thanks, Mike!
I am currently exploring algorithms to estimate sleep-wake states and I am interested to know more details on two columns in the MESA actigraphy dataset: "Awake indicator" and "Interval".
The Awake indicator seems to be estimated by an automatic algorithm. If so, do you know what algorithm was used?
The Interval seems to be a post-processed version of the Awake indicator. Is it correct? If so, was it manually annotated?
Thank in advance!
I am aware that, currently, MESA and HCHS/SOL datasets have both PSG and actigraphy data, but I could not find a way to synchronize the PSG and the actigraphy data in any of these datasets.
Is there anyway to know when the PSG started being recorded and align it with the actigraphy data?
Thanks in advance,
