To obtain error-free auto-labeling, before running any calibration operation, ensure that the labels are present and correct in your .vst file and that you have labeled your ROM or static trial. If the markers in your ROM or static trial are not labeled, the calibration operation will fail. If your markers are incorrectly labeled (for example, if left and right markers are swapped), calibration will succeed, but when the Vicon Skeleton (.vsk file) is used to automatically label your movement trials, it will continue to produce the erroneous labels.
To address this, check your labeling carefully. You can correct any swapped markers with the Swap Marker Labels button in the Label/Edit Tools pane.
To correct swapped markers:
- Select the two swapped markers in either the 3D Perspective view or in the Subjects Resources pane.
- In the Label/Edit Tools pane, in the Manual Labeling section, click the Swap Marker Labels button.
