Data Collection and Analysis for Circadian Biology
Does it take you longer than 30 seconds to measure phase shifts? If so, ClockLab, the industry standard for the collection and analysis of circadian activity data, can help. It combines a point-and-click interface with state-of-the-art algorithms. Embedded controls turn each graph into a powerful interactive tool for data analysis. Our users enjoy ClockLab’s speed and convenience. ClockLab’s Analysis program has been applied to mice, hamsters, rats, sheep, Drosophila, humans, bees, ants, algae, Eurasian lynx, grizzly and polar bears in the wild, Alaskan squirrels in the wild, gopher turtles in the wild, horseshoe crabs, tuco-tucos, molluscs, mosquitoes, and soil chemistry signals from the Mars Viking Lander.
The ClockLab suite consists of three independent applications: the Data Collection program, the Analysis program, and the Chamber Control program.
ClockLab Analysis 6 is a new, stand-alone program that does not require Matlab to run. The interface has been updated to include many new features, and new analyses have been added.
- Automated detection of activity onsets for period estimation
- Activity Profile with Least Squares sine-wave fit, F statistics and p-value estimation (Cosinor).
- Periodogram: Chi-squared, F, and Lomb-Scargle
- FFT and Wavelet Analyses
- Bout analysis
- Click-and-Drag over actogram for easy navigation through long records.
- Phase shift measurements from detected onsets
- Non-Parametric Circadian Rhythm Analysis (NPCRA)Non-Parametric Circadian Rhythm Analysis (NPCRA)
- Batch Export analyses for multiple files either to spreadsheet files or directly to Excel
- Batch print graphs for multiple files, either 1 to a page or multiple graphs to a page
- Access data in multiple formats, including ClockLab, Actiwatch, Dataquest, Minimitter, Trikinetics and many others
- Windows and Macintosh compatible
- Actogram plot colors and styles can be set by the user
- Context Help: Hover over a control to display text regarding its use
- Keyboard shortcuts for common functions (Open, Next File, Previous File, etc.)
ClockLab Data Collection incorporates a large array of features at reasonable cost:
- Up to 448 channels on a desktop or laptop computer

ClockLab Performance Monitor. ClockLab can send status messages to the Actimetrics servers at regular intervals. If problems develop with the ClockLab computer, the program itself, the interface hardware, or if any animals become inactive, the server will notify designated users by text or email within 20 minutes. Contact Actimetrics for details.
ClockLab Chamber Control is the software interface for light-tight circadian cabinets from Phenome Technologies.
