There is one script for the Light/Dark preference test for adult zebrafish.
There is one asset you will use which splits the tracking arena into two separate target zones. The darkened area is approximately 50% of the tank and the light area is approximately 50% of the tank.
See the protocol page, Light/Dark preference test (zebrafish) for more details on the assay.
You will need to upload the asset into the Asset directory on your Zantiks Control Console and ensure the correct asset name is in the LOAD(DETECTORS,"name_of_asset") and the LOAD(ARENAS,"name_of_asset") command in the script.
