Joint Center Localisation

Hello everybody,

I am a industrial engineering student from Germany working on a biomechanical analysis via OpenSim as my master thesis.
My task is to analysis the localisation of joint centers while sitting on a motor cycle. Unfortunately I have not found a way to calculate the coordinates of joint centers. After scaling and IK I only got the joint angles but no three dimensional coordinates.

Therefore my questions are:

1. Is it possible to calculate and export the exact joint center coordinates in OpenSim?
2. If yes, how can I calculate them?

Thanks for helping me!!
