Activity ProfilesDragable
cursors control the alpha and rho periods
and a display of counts
that occurred within these periods (not shown). Counts for alpha
and rho in each day can be exported to a spreadsheet file. X-axis
units can be set to Hrs, C-Hrs, Degrees,
or %Tau. SEM can be displayed for each
point as a shaded areas around the plot line. Mean and median
activity levels can be displayed as a horizontal line. |
 |
PeriodogramsClockLab can make Chi-square, F or Lomb-Scargle periodograms. Peaks are detected and labeled as shown (blue rectangle). A button in the window applies this TAU to subsequent actograms and activity profiles. Significance level (green) can be adjusted. The periodogram can be zoomed in to view the peak in detail by clicking and dragging across the image. |
 |
FFTsBoth power spectra and amplitude spectra can be plotted, with or without prior filtering (Blackman-Harris Window) to reduce artifacts. The FFT can be zoomed in to view the peaks in detail. Shift-clicking on a peak displays its amplitude, frequency and period. The period of the largest peak is identified automatically (blue rectangle). |
 |
AutocorrelogramAn autocorrelogram of the data can be plotted. The peak period can be identified by shift-clicking on the peak. The graph can be zoomed. |
