TRU SCAN is a versatile and simple system to monitor open field tests. In the TRU SCAN software, the experimental protocols are setup through a simple point-and- click user interface, saved and recalled by number for future use. All selected data is compiled and analyzed according to the parameters defined in the protocol. Versatility and simplicity are the defining benefits of TRU SCAN. All selected data is gathered, analyzed and presented in the same way whenever the experimental protocol is run without reselection. The software also features subject, operator and protocol IDs as well as automatic data storage and stimulus presentation, if desired. Data analysis is fully automated for each subject or across subjects with results presented in a table or graphically. Results are calculated for all userselected parameters. Graphical data can be copy-pasted directly into publication documents. Data is stored as raw coordinate sets with real time date stamps for each of the sensor rings used. This allows experiments to be re-run without animals to re-analyze data, using more and shorter histogram bins or new data elements to find other behaviors or effects not observed in the original analysis. This unique feature minimizes the number of animals needing to be tested. Raw data may also be easily exported to a spreadsheet for further statistical analysis. TRU SCAN 2.07 software is compatible with the following Operative systems:
