Choose Setup > Trial List.

Defining Independent Variables

Enter your independent variables such as:

• Subject ID with the ID of your animals as predefined values.
• Phase with Acclimation, T1, T2 as predefined values, where:
  • Acclimation to mark trials where the animal is free to explore the arena, with no objects present.
  • T1 to mark trials where the animal is presented with a pair of identical objects.
  • T2 to mark trials where one of the familiar objects is changed for another new (novel object test).
• Treatment with Treated and Control as predefined values.

If you want, you can predefine all your trials here, or you can enter the independent variable values as you carry out the trials. You can also prepare the trials in Excel, randomize them and then paste the values into your Trial List.

Furthermore, you can define a list of trials for batch acquisition. See Batch Data Acquisition in the EthoVision XT Help.

Detection and Tracking Settings

When detection is not satisfactory, select Rodents / For Occlusions as the tracking method and repeat the detection setup steps.

Note: If you want to use the Deep Learning technique to track the subject's nose, note that there are additional requirements and limitations. Among other things, you need a powerful graphics card. See Deep Learning: Requirements and Limitations in the EthoVision XT Help.
