# Live Mouse Tracker: Create an experiment

Aim

To create an EthoVision XT experiment that is compatible with the Live Mouse Tracker behavioral data acquisition system.

Background information

An EthoVision XT experiment set to Live Mouse Tracker is a modified version of a standard, multi-subject, multi-body point experiment, with predefined, permanent settings. The main characteristics are:

▪In the Experiment Settings, the Video Source is Video file, the Number of Arenas is 1, the Number of Subjects is 4 and under Tracked Features the option Tracker add-in is selected. We recommend not to change those settings. You can, however, change the settings under Units.

▪In the Arena Settings, the arena is already calibrated using the scaling factor of Live Mouse Tracker. If you like, you can add zones for analysis beyond the standard readouts of Live Mouse Tracker.

▪Trial Control Settings, Detection Settings, Acquisition, and Track Editor have been removed because they are not relevant in Live Mouse Tracker.

▪All analysis functionalities of EthoVision XT are kept. So you can, for example, analyze the tracks obtained with Live Mouse Tracker combined with zones using a Data profile, or combine Live Mouse Tracker readouts with the EthoVision XT analysis variables.
