# Prepare the trial list for batch acquisition

Aim

To make a list of the trials to be acquired in batch, either live or from video files.

Prerequisites

▪Click the Show/Hide button on the toolbar and select Variables. When you track from pre-recorded video files, make sure that Video file is selected.

▪Optionally select to display Arena settings, Trial Control settings and Detection settings.

Prepare the Trial List for batch acquisition

1.Add the trials you need.

2. optional If you defined multiple Arena Settings, Trial Control settings or Detection settings: for each trial select which settings you want to use. Either select settings for all the trials or for none at all.

tip If you want to use the same Arena Settings, Trial Control settings or Detection Settings for all the trials, select them in the Acquisition Settings window.

3.Add video files to the planned trials, either automatically or manually. See the options below.

You can either select different video files for different trials or the same video for multiple trials. Choose the latter way of working if you made a long video with multiple trial recordings. If you choose the same video, EthoVision will start tracking at that point in the video where the previous trial stopped. To make sure that tracking starts and stops at the correct time point, you must define appropriate Trial Control settings.

Automatically add video files to the Trial List

1.Click the Add Videos button on the toolbar.

2.In the Add Videos window, select the video files you want to use and click Open.

3.Select one of the options under Sort order and click OK:

Date-time order. Selecting this option links the video file with the earliest date/timestamp to Trial 1, the next video file to Trial 2, etc.

Alphabetical order. Selecting this option links the video files to the trials in alphabetical order.

Manually add video files to the trial list

Click one of the cells in the Video file column. In the Select Video window, select the video file and click Open. Do this for the other planned trials.

Notes

▪If you select more video files than the number of planned trials in the Trial List, EthoVision will add additional trials to the Trial List.

▪If you manually linked videos to some of the planned trials, and for the remaining trials you use the automatic option, EthoVision only fills the gaps, that is, it adds videos to those trials which do not have video references yet.

To carry out batch acquisition

Choose Acquisition > Open Acquisition. In the Acquisition Settings window, select Track all planned trials.
