# Undo track edits

Aim

To revert to previously saved data after you have changed the data further and you do not want to keep the last edits.

note The procedure below is also valid when you edit data in the Manual Scoring screen. There you also find the Save and Undo buttons.

Prerequisites

▪In the Track Editor, or in the Manual Scoring screen, you have done edits after saving the data at least one time.

Procedure

1.Click the Undo button on the toolbar.

Result: A message appears, asking you whether you want to lose the changes since the last save.

2.If you click Yes, the original track plot is restored.

If you click No, you return to the main screen without losing the changes.

Notes

▪To return to the original data, click Undo all. However, keep in mind that you lose all changes.

▪If you edit data in one trial and then select another trial in the trial selection list on the toolbar, the changes you have made to that trial are saved automatically, including those you made after saving.

▪If you open another EthoVision XT screen, for example, to calculate statistics, or close the experiment after making changes to the track, those changes are saved, and retained when you switch back to the Track Editor screen. However, the saved copy (restore point) is always deleted when closing the experiment. Therefore, you cannot revert to the saved copy.

Consider the following sequence of actions:

1. Edit data, then click Save.

2. Make a second run of changes, then close the experiment.

3. Re-open the experiment and choose Acquisition > Edit Tracks.

The screen shows also shows the second set of changes made, but you cannot revert to the saved copy (restore point).
