I am working on a project for which we need to determine the shoulder and elbow angles of a subject in real time for feedback control. Is it possible to custom define the marker IDs? For example, if I want to know where a specific pointA is, can I define a marker as pointA such that I can easily use its data in code?

Thanks for your help.

Unfortunately, no. You can define multiple markers as a rigid body, however, and get either the centroid position or individual RB marker position from Tracking Tools as a fixed name, though.

Thanks for your response Mike. Just so I'm sure I understand, I can name the markers that compose the rigid body? And if that is correct, how exactly would I do that? Thank you

The names aren't assignable, but they are static. You could create a rigid body called "shoulder" and get either the centroid for shoulder or shoulder 1, shoulder 2, shoulder 3, et. cetera.

Thanks Mike.
