There is one script for the Open field assay for adult zebrafish.
There is one asset you will use which should 'divide' the testing tank into two arenas: a central target zone and an outer perimeter target zone.
See the protocol page, Open field test (adult 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") command in the script.
See the Calibrating your Zantiks unit page and Asset building in the AD unit page or Asset building in the LT unit page for details on how to create assets customised to your system.
