Hi,

In SHHS dataset, we have two EEGs, called EEG and EEGsec, I want to know which of them was recorded from channel C3 and which of them from channel C4?

Thank you very much in advance for any guidance.

Thanks a lot

Thank you so much for your response,

It seems I have made a mistake about the values that light signals can have, the values are only 0 and 1; however, I am wondering if the value of 1 refers to when lights off (or dark time) during the sleep and the value of 0 refers to when the person turn on the lights for a reason such as going to the restroom, or because of insomnia, ...? Is it a correct inference? I mean, When light signals get values of 1 and when their values change to 0 ?

Thank you for any guidance.

Dear NSRR team,

I would like to know "in more detail" about the light which has been recorded in SHHS, and exists in PSG files. I have some questions about that: What is the meaning of recorded light exactly? what does the light refer to? What is the meaning of values of 0, 1, 2, and 3 that light signal has for each second? what is the meaning of theses values ( 0, 1, 2, and 3)? Where can I get precised information about this signal of PSG files (light) from?

Thank you so much

Dear NSRR Team,

I have the 0.13.1 version of dataset completely, but I don't have .CSV files regarding STAGES. I would appreciate it if you help me know how I can access to them.

Thank you very much for any help
