The "Display" panel is used to select the elements to display in the central part of the "Current test" view:
Video / Tracking:
oCenter: the point identified as the center of the detected animal. The point corresponds to the position of the animal.
oHead : The position of the animal's head (if the " Detect animal's head " option is selected in the protocol)
oTemporary track ( Center or Head ) : the part of the path traveled by the animal around the current image ( 15 points before, 15 points after ).
oTrack (Center or Head) : The path taken by the animal throughout the analysis.
oPartial Track (Center or Head) : The path traveled by the animal between the start of the analysis and the current video frame.
oDirection/Speed : Vector indicating the direction in which the animal is moving and its speed.
oBehaviors : The position of the periods of the behaviors (only if the test is analyzed and the period is located during the analysis period).
oArena / Zones : The arena and the different zones defined in the protocol.
oAreas visited : the areas visited by the animal are highlighted.
oBlob : square box that delimits the area where the animal has been detected.
oAnimal : area that corresponds to the part of the image where the animal was detected.
oCountdown and recording icon : countdown before the start and the end of the recording and flashing icon during video recording ( This option only appears for tests waiting to record with a webcam ).
oVideo : the video in the background.
•Curves:
oSpeed: speed of the animal calculated on the position data after applying the smoothing algorithm chosen in the smoothing options of the experiment .
oSpeed (raw data): animal speed calculated based on raw position data (before smoothing).
oMovement: periods when the animal is moving (according to the criterion defined in the General tab of the Protocol ).
oZones: periods when the animal is present in a zone.
oUndetected animal: periods when the animal is not detected.
oBehaviors : periods of behavior
When adjusting detection parameters, the following elements can be displayed on the video :
•Video / Tracking:
oArena: The arena defined in the protocol.
oSize of detected areas : For each detected area, the area's surface value.
oAreas that could correspond to an animal : The areas of the image detected by the detection module that could correspond (by size and shape) to an animal.
oAreas that could not correspond to an animal : The areas of the image detected by the detection module but that cannot correspond to an animal due to their size or shape.
oVideo : The background video.
Note: The selection of elements to display is specific to each protocol.
Some display elements are configurable (color, line width, etc.). To do this, double click on the element in the "Display" panel or use the popup menu to open the corresponding dialog box:
Head, center:
This dialog box allows you to choose the color and size of the point that marks the position of the center or the head.

Track, contour, speed:
This dialog box lets you choose the color and style of a track, animal outline or velocity curve.

Animal, movement, undetected head :

Undetected animal :

On principle, the animal is not detected in hidden areas. These periods of non-detection are not displayed in the graph area by default. To display these periods, simply uncheck the "Hide in hidden areas" box.
Visited zones :
This dialog box allows you to configure the display of the zones visited by the animal.

Color: the color applied to the area. You can use the color of the zone defined in the protocol or choose another color.
Transparency: the transparency rate of the color. 0 = opaque. 100% = totally transparent.
Behaviours :
This dialog box is used to configure the display of the position of the behavior periods (only the periods that are located during the analysis period).
.png)
You can choose to display the positions:
from the beginning of the period.
from the end of the period.
from the middle of the period.
over the entire period. In this case Ethotrack displays several markers over the entire period between the start and the end of the behavior. The markers are separated by the specified distance (5 centimeters in the example).
You can also configure the size of the position marker. In the case of a size "according to the duration of the period", the size of the marker varies according to the duration of the period:
very small if the duration is less than 1 second.
small if the duration is between 1 and 2 seconds.
medium if the duration is between 2 and 5 seconds.
big if the duration is between 5 and 10 seconds.
very big if the duration is greater than 10 seconds.
Areas that could correspond to an animal :
This dialog box allows you to configure the appearance of detected areas when their size and shape could correspond to an animal.
For detection to be accurate, only one area should be able to correspond to an animal.

Areas not corresponding to an animal :
This dialog box allows you to configure the appearance of detected areas that cannot correspond to an animal due to their shape or size.
.png)
Countdown and recording icon :
This dialog box allows you to configure the display of informations during video recording :
•Countdown timer before recording ( as defined in the protocol ) and programmable countdown timer before recording ends.
•Flashing icon during recording .png) .

Notes : these settings are also used for display in the "current video" view.
