When I conducted a further sleep stage analysis, then I needed to add the EOG signals. But in the website PSG (https://sleepdata.org/altamira?slug=ccshs&path=polysomnography/edfs/ccshs-trec-1800001.edf&window=300&page=1&auto=.) I didn't know which one is the EOG signal, could you lend me a hand again?
Million thanks, I will try it.
Great thanks for the data provided at first. Currently, I am trying to transfer the Sleep-related EDF file through EDFBrowser and the Matlab edfread function, but both the results only contain the signal data without the Hypnogram information on the top of EDF file. Could you land me a hand about how to obtain the Hyponogram (annotation information) to deal with the result evaluation.
My EDF file address is here, https://sleepdata.org/datasets/cfs/files/polysomnography/edfs
