Aim
To specify the number of enclosures (arenas) that you use during a trial.
Prerequisites
▪Your EthoVision XT license includes the Multiple Arenas Module. See Upgrade EthoVision XT
▪You want to track animals in two or more arenas simultaneously.
Procedure
1.Choose Setup > Experiment Settings.
2.Specify the Number of Arenas in the video image.
Notes
▪Examples of multiple arenas: a well plate with 96 wells; two apparatuses for a novel object recognition test placed one next to the other; four open fields; 4 or 16 PhenoTypers.
▪It does not matter how many cameras you use. If you use for example four cameras, each pointing to an open field, select 4 as the number of arenas.
▪With the Base version of EthoVision XT you can track one subject in one arena. With the Multiple Arenas Module you can track in up to 100 arenas simultaneously.
▪important If you want to use more than one arena, first check that no samples are missed during acquisition before deciding to work with live tracking. You can display statistics on missing samples during acquisition, in the Analysis Results and Scoring pane, in the Trial Status tab.
