Open Field Activity System Features:

All experiments and subject data are entered into a database, with all subject data linked together. This allows the software to track everything, from automatically sequencing sessions to using the researcher's selection of available data parameters, and save it based on the assigned Subject ID.
Up to a 50 ms scanning rate. This rate virtually eliminates phasing or aliasing of the stereotypic movement data and provides the highest resolution possible.
All standard data are displayed in real time along with a cumulative plot of the subject's activity for all chambers.
Experiment setup is made easier with a one screen setup, and allows one to choose the size of the chamber, thus allowing for distance traveled to be in real units (i.e., inches or centimeters) instead of beams broken.
Automated file naming uses experiment, group and subject information to generate datafiles since all session data are automatically appended to existing data files. If you prefer, however, you can always choose a custom filename.
Newly added rotational analysis option. You can choose to examine large (wide) or small (pivotal) rotations, allowing for rotational measures to be obtained on staggering, ataxic, lesioned, or other locomotor impaired mice or rats.
The Windows-based software includes improved zonal analysis, the ability to change boundaries around the animal in post analysis, and the addition of velocity and ambulatory episodes. This can be done with saved data at any time.
