Data Analysis and Collection 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, drosophila, humans, bees, algae, Eurasion Lynx in the zoo, radio-tagged squirrels in the wilds of Alaska, horseshoe crabs, and soil chemistry signals from the Mars Viking Lander.
ClockLab's data collection program incorporates a large array of features at reasonable cost:
Up to 448 channels on a desktop or laptop machine
USB interface for instant setup
Integrated light control and light recording
High-density switch connections
Remote data access via internet
Record switches, motion detectors, Minimitter ER-4000's
Paste actograms and other plots into presentation graphics programs like PowerPoint, Illustrator or Photoshop. Every graph is completely editable.
Automated detection of activity onsets and offsets makes it possible to
Measure phase shifts
Measure mean alpha
Predict future activity onsets... all with a few mouse clicks.
Zoomable actograms for easy navigation through long records. Just drag on an interesting part of the actogram to zoom in. Then click to display the periodogram, FFT or activity profile for the chosen data segment.
Chi-squared periodograms, activity profiles, FFT's and auto-correlograms.
Export all data and analyses to spreadsheet files.
Access data in many formats, including...ClockLab format, Stanford Software's Chronobiology Kit, Actiwatch, Dataquest, Minimitter, Trikinetics and others.
Extensive batch processing capabilities for printing and analysis.
Analysis program (Circadian Toolbox)
A single-computer license for the analysis program can be purchased on its own. It requires the purchase of Matlab (The Mathworks, Natick, MA). Only the basic Matlab is required. Toolboxes, simulink, the compilers and Excel Builder are not required. The Student verison is not recommended and will not work for large data files.
Complete system (Data collection and analysis)
1 56-channel interface box
2 56-channel interface box
3 56-channel interface box
4 56-channel interface boxes
8 channels per interface. Up to 100 additional channels available with special purpose output hardware
Minimitter E-Mitter recording module.
Hardware available separately from Mini-Mitter. Ordered as add-on to 56 or more channel-system.
Preloaded software, data acquisition boards and drivers (Monitor not included).
Complete system setup
We will help identify and install chambers, cages, wheels and other sensors.
Multi-computer site license for the ClockLab Analysis program is available with each data collection system.
Upgrades of the data collection and analysis program are free for 3 years.
The data analysis system runs on Windows 2000/XP and requires only the basic MATLAB program (no toolboxes or Simulink necessary) from The MathWorks, Inc. if your institution does not already have a site license available.
Data collection requires a computer running Windows 2000/XP with a clock speed of 500 MHz or greater and 128 MB memory. Monitor resolution of 1024x768 or better. Zip drive , flash memory stick or network connection recommended for accessing files during data collection.
