We are working on sleep stage classification using MESA and MROS dataset, but during the process we find that label of epochs some of the subjects was 9, which was not mentioned in the PSG scoring manual like (0-Wake, 1- N1, 2 - N2, 3or4 - N3 and REM -5). Please help us with the meaning of label 9 obtained for some epochs as mentioned above.

The 9 value indicates "Active", which could be recoded to wake. Thanks for using the site!
