I recently got access to the HCHS data set, and wish to study the hypnograms (I don't need the raw data, really just the scorings). So far, I have not been successfull in getting lunaC to extract the hypnograms directly from the xml files. Should that be possible? Or do I have to download all the edf files too?

Right now, my 'result' looks like:

➤ luna --xml hchs-sol-99868795-nsrr.xml

error : bad EpochLength

Ok, so, I now understand that when the data set is supposed to contain 'polysomnography', that is not quite true, and the data recorded would not be suitable for sleep scoring. So it seems there are no hypnograms inside this....

Hey - sorry about that. HCHS used a sleep monitor with limited capabilities. I see your new data request came through, hopefully you'll hear about that one soon. Thanks for using the site!
