# Duplicate an arena

Aim

To make copies of an existing arena in the same video image. For example, in an experiment with four PhenoTypers, draw an arena for cage 1, and then copy that arena for the other three cages.

important Before duplicating an arena, make sure you have created all the zones for that arena.

To define arenas in DanioVision experiments, see the DanioVision DVOC-0041 - Reference Manual, which you can open from the Apps screen under Noldus > EthoVision XT 19 Other Documentation.

Procedure

1.In the Arena Settings window, click the row for the arena you want to duplicate.

2.Click the Copy Arena button, or right-click the row and select Duplicate Complete Arena.

3.In the Duplicate Arena window, select an option from the drop-down list. If you select the option All other arenas, also select how the arenas are arranged in rows and columns. The multiple arena setup now opens.

4.Select Duplicate content to existing arenas if you want to duplicate zones and points to the other arenas.

5.Move the duplicated arena to the appropriate location.

6.Repeat steps above for all consecutive arenas.

7.Adjust the position, shape and size of individual arenas. See Move, rotate and resize a shape.

8.If the arenas are evenly distributed in the video image, use the The Multiple Arena Setup to move, scale, rotate and space all arenas.

Notes

▪To duplicate an arena, you can also right-click the outline of the arena and select Duplicate.

▪When you copy an arena, calibration is also duplicated if it is unshared. See Calibrate multiple arenas.

▪An arena to which another arena is duplicated, loses its previous definitions and contents.

▪If you select the option Duplicate content to existing arenas, the position of existing arenas is maintained. If you do not select this option, the position of each arena is adjusted based on the number of arenas and their layout. See The Multiple Arena Setup.
