# Move points

Aim

To change the X,Y coordinates of a point on the track plot.

Procedure

1.Hover the mouse on the point you want to move. The mouse cursor changes to a four-headed arrow.

2.Press and hold the left mouse button and drag to the position you require.

3.Release the mouse button. The point is moved to the new position and its X,Y coordinates are updated in the Samples List.

4.To de-select the point, press Esc or click on the background image.

Notes

▪If you move a missing sample, this becomes non-missing and therefore included in your data.

▪You cannot move a sample outside the arena.

▪If your experiment is set to Center-point, nose-point and tail-base detection, a sample is made of three points (no matter whether those are actual data points or missing). You cannot move a sample as a whole, you must move each point separately (center-, nose-, and tail-base points).

▪If you move the nose-point, the corresponding value of Head direction for that sample is unchanged.
