Editing Behavior Scores

Extend a Color Bar to the Current Position

1. Hover with mouse over the existing color bar, right-click and choose Extend to current, or double-click the existing score.
2. Result: The color bar now ends at the specified time.

Fill the Gap Between Two Behavior Scores

Follow this procedure if you scored two instances of the same behavior, and you want to fill the gap between the two instances since they actually refer to one bout of behavior. The frequency of the behavior will be reduced by 1.

1. Position the video at the start of the second color bar.
2. Point to the first color bar, and double-click or right-click and select Extend to current.

Create a Gap Between Two Behavior Scores

This applies to Start-stop behaviors only.

Follow this procedure if you scored an instance of a Start-stop behavior, and you want to insert a gap between the original start and end points. The frequency of the focal behavior will increase by 1. The gap will appear as Not [behavior name] in the analysis.

1. Click the Start scoring mode button.
2. Position the video to where you want the end of the gap (= the second start point of the behavior).
3. Click the button for the behavior.
4. Play the video backward. Use the frame-by-frame controls for accurate scoring. Pause the video at the start of the gap (= the first end point of the behavior).
5. When finished, click the Stop scoring mode button.

Reduce the Duration to a Specific Time Point

Follow this procedure if the behavior score is too long relative to what is shown in the video. Do one or both of the following, depending on whether the color bar occurs before (a) or after (b) the actual behavior in the video, or both (a) and (b).

(a) Crop from the left side:

1. Position the video where the behavior starts.
2. Point to the color bar at the left of the hairline. The mouse pointer turns to a delete symbol on the left side.
3. Right-click and choose Crop to current, or double-click the color bar.
4. Result: The color bar is shortened.

(b) Crop from the right side:

1. Position the video where the behavior ends.
2. Point to the color bar at the right of the hairline. The mouse pointer turns to a delete symbol on the right side.
3. Right-click and choose Crop to current, or double-click the color bar.
4. Result: The color bar is shortened.

Note: Which side of the color bar is deleted by Crop to current depends on where the mouse pointer is located relative to the hairline.

Replace a Behavior With Another One

Aim

To replace the score of a behavior with that of another behavior from the same Mutually-exclusive group.

Prerequisites

• You scored behaviors of a group defined as Mutually-exclusive. See Define the Behaviors That You Want to Record Manually.
• 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. To enable the scoring mode, click the Start scoring mode button. Before editing existing data, click the Save button on the toolbar. This will save a copy of the current behavior scores. In case you make mistakes when editing, you can always revert to that copy by clicking Undo. For more information, see Saving the Track Edits.
3. Position the video to the point where the new behavior starts.
4. Click the button for the new behavior.
5. Play the video forward. Use the frame-by-frame controls for accurate scoring.
6. Pause the video when the behavior ends.
7. To confirm, click the behavior button again. To quit editing, click the Stop scoring mode button.

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. 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. When deleting point events, make sure that the hand cursor is slightly to 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.
• You can only delete a behavioral category defined in the Manual Scoring Settings after deleting all the trials. Note that if you remove all trials, you remove all your data. See Edit the Manual Scoring Settings.

Score Behaviors in Different Arenas

Aim

To edit behaviors manually for subjects that were tracked in different arenas.

Prerequisites

• You have defined two or more arenas in the Arena Settings.
• You have defined behaviors in the Manual Scoring Settings.
• You have acquired one trial and its corresponding video.
• You have opened the Manual Scoring screen (Acquisition > Manual Scoring).

Procedure

1. In the Manual Scoring screen, select the arena in which you see the subject you want to score behaviors for. Result: The body points of the subjects in the selected arena are displayed.
2. To enable the scoring mode, click the Start scoring mode button.
3. Score or edit the behavior for the subjects in that arena. See Score Behaviors Manually After Acquisition.
4. Repeat the procedure for the remaining arenas.
