When the experiment lasts several days, or even several weeks, it may happen that the camera or the workspace are accidentally moved. In this case, when recording a new test, it is possible to see that the position of the arena defined in the protocol no longer corresponds to the real position of the arena in which the animals are evolving.
The position adjustment marks make it possible to correct this problem simply and automatically.
To do this, simply position 2 colored marks on the enclosure in which the animals are evolving. These 2 marks must respect the following constraints :
• be of a solid color that is neither found on the animals nor on the bottom of the enclosure.
•be of a sufficient size to be detected (approximately 1 or 2 cm on each side).
•be securely fixed to the enclosure in 2 opposite corners.
•be visible on the first image of the video.

2.Click the image in the center of the first color mark .png)
3.Click the image in the center of the second color mark .png)
