This data is accelerometry data from devices participants in the test group wore on their wrists. The first six characters identify the participant. These files are output from an Actigraph native scoring of sleep (Cole Kripke). The first three rows are a header and should be skipped. After that the first column is date, the second time, the third Axis 1 counts. The final column is the sleep or wake determination. This column can be ignored or dropped and the data could be scored by our R based algorithm.
