Actimetrics ClockLab Analysis Package

Model 86188


A widely used stand-alone program for the analysis of circadian rhythms. It can read and analyze records obtained from almost any circadian data collection system, including the ClockLab data collection program.


ClockLab Analysis 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 automatically reads data files from many data collection systems: ClockLab Data Collection, ClockLab Wireless, LumiCycle, Trikinetics, CamNTech, Actiwatch, DataQuest, Condor, VitalView, Sable Systems, Columbus Instruments, and more. It is also possible to create data files that ClockLab can read using a simple text-based or CSV format.
