When your variable scheme is finished, you can use it to update VSK with your new joint centers and segment locations.

To update a VSK with the variable scheme:

  1. In Nexus, create a subject in the normal way (ie, from a labeling template VST file), and enter the required subject measurements.
  2. Capture or load a static trial, and label it, either by using the Autolabel Static Frame function, or manually.

    Important
    It is NOT necessary to run the other operations that scale/calibrate the subject.
  3. When the static trial has been correctly labeled, save the trial by clicking the Save button, so that both the subject's VSK and the C3D are saved.
  4. In ProCalc 1.3 or later, load the trial, then on the  Input Parameters tab and the Variables tab, select the scheme that you want to use to update the VSK.
  5. On the Data Management tab, click the Update VSK button.
  6. Review and accept any prompts that are displayed.
    When the operation starts, information about the progress is output to ProCalc's log.
  7. In Nexus, do one of the following:
    • Nexus 2.9 and later: Right-click the subject and select Refresh Subject then From VSK.
      or
    • Earlier versions of Nexus: Exit the session and open the session again (or re-start Nexus).
  8. In the Subject Viewer, make sure that the subject is updated. 

You can now use the updated VSK to:

  • Label dynamic trials.
  • Generate kinematics in real time or offline.
    To generate the VSK kinematics, either click the Nexus KinFit button  or run the Kinemetic Fit pipeline.
