Automated Identification of Activity Onset Times

The red dots show the results of the automated onset-time calculation, available instantly at the touch of a button. The calculations are 95% correct for most data. In this example, two or three of the times need to be edited, which is done simply by clicking on the appropriate point within the line for a given day. The underlying actogram is automatically dimmed to increase the visibility of the dots. With the onset times identified, several useful calculations are now possible, such as prediction of onsets on subsequent days, calculating TAU and calculating phase shifts.
