# Delete a manually-scored behavior

Aim

To remove an instance of behavior scored manually.

Prerequisites

▪You have opened the Manual Scoring screen (Acquisition > Manual Scoring).

Procedure

1.Choose the trial, and when it applies, the arena in which you want to score behaviors.

2.Hover with the mouse on the color bar (or vertical segment) which represents the instance you want to delete. The cursor changes to a symbol depending on where this instance is relative to the hairline.

tip If you are not sure of the results of editing, click first the Save button on the toolbar. You can always return to the last saved data by clicking Undo. See Saving the track edits

3.Right-click and choose Delete event.

4.The same is valid for point events:

tip When deleting point events, make sure that the hand cursor is slightly at the right of the event you want to delete.

Notes

▪If you delete a behavior from a mutually-exclusive group, the previous behavior is extended up to the end of the color bar that you delete.

Result:

▪You can only delete a behavioral category defined in the Manual Scoring Settings, but only after deleting all the trials. Note that if you remove all trials, you remove all your data! See Edit the manual scoring settings
