ClockLab Activity Profile

The Activity Profile shows the average of activity across selected days.

The shading around the activity profile line plot shows the standard deviation of the activity at each point in time.

The red line is a sine-fit to the waveform. Parameters describing the fit are shown in the table to the left, including amplitude, phase, mean and median. In addition, parameters of the Cosinor analysis are listed, including MESOR, the F statistic and an estimate of p-value, which for such a robust rhythm as shown here is arbitrarily close to zero.

The “Position” and “Counts” indicators at the bottom right show the positions of the two vertical black cursors in the image and the total number of counts for the points between the cursors (alpha counts) and outside the cursors (rho counts).
