Data analysis
In-depth analysis of your data
EthoVision XT does not stop after collecting the data. You can also use EthoVision XT to perform in-depth analysis. The number of parameters that can be used is substantial, including trial duration, in zone, distance to zone, distance to zone border, distance moved, velocity, heading, turn angle, angular velocity, mobility, proximity, rotations, elongation, etc. Statistics include mean, variance, standard deviation, standard error, minimum, maximum, sum, total, number of samples, etc.
For instance: use elongation, mobility, and head direction parameters when you are performing a novel object recognition test, a plus maze test, or a fear conditioning test. The stretch-attend posture, characterized by elongation of the animal’s body, is often considered a response to an object that incites fear or curiosity. Additionally, time spent immobile serves as a measure of fear. The rotation parameter is very useful in research on brain defects.

You can zoom in into tracks or parts of tracks by the powerful data selection criteria EthoVision XT offers. Selecting data in which animals received a specific treatment allows you to only analyze those data and ignore others. Or nest your data on time, zone or a behavioral state. The results can be visualized in a time-event plot together with the track data and the video file. This way you get an instant feel for your data. Analysis results are also represented in a table. Of course you can export your (raw) track data for further analysis with statistical software programs.
