Reconstruct and label movement trials
- Gisela Roberts
- Ben Stanley
After you have calibrated a labeling skeleton for your subject (see Prepare a subject) and captured the required movement of the subject in a trial or series of trials (see Capture movement trials), you must reconstruct and label the raw camera data to create 3D markers. You can do this as a separate step, as described below, or you can specify a pipeline that includes Reconstruct and Label in the Post-Capture Pipeline Setup (see Capture the required movement), so that these operations run straight after capture.
Note
You can choose to reconstruct and then label separately, or run both operations together, by clicking either the Reconstruct button 
or the Reconstruct and Label button 
on the Nexus toolbar, or by configuring and running the equivalent pipeline operations. Normally, you would use Reconstruct alone if you are working on a labeling skeleton template (VST), but Reconstruct and Label if you are processing movement trials.
To reconstruct and label trial data:
- Display the subject whose data is to be reconstructed in either of the following ways:
- If you have just captured a trial, ensure that the raw marker data for the subject in the capture volume is still visible in a Camera view and in the Resources pane, ensure Nexus is in Offline or Pause mode; or
- On the Data Management tab, open the desired trial file containing raw trial data for the subject.
- Do one of the following, depending on whether you need to adjust the reconstruct and labeling settings:
- To run the operations without viewing and changing their settings, on the Nexus toolbar, click the Reconstruct and Label button.
This runs the Reconstruct and Label operation defined in the Pipeline Tools pane.
Or - To view and/or change the operations, on the Pipeline Tools pane, from the Current Pipeline list, select Reconstruct And Label. In the list of current operations, click on Combined Processing to select it. set the Processing Output level to the required level, for example, Labels, and specify any other required properties.
The pipeline progress bar indicates when the operation is complete. - To run the operations without viewing and changing their settings, on the Nexus toolbar, click the Reconstruct and Label button.
You can now review the results and fill any gaps in the trial data. For information, see Review trials and fill gaps.
