Opensim Coordinate Tap and rotation relationship

Hi all,
In opensim, we can use the slide bar in the Coordinate Tap to change the Coordinate values. How the changes of these values relates to rotations(rotate about which frame for how many degree)?
Regards,
Hilary

That will depend on how the joint is modeled. You can open the model in a text editor and read it to find out.
This paper is also probably worth reading.

Hi,
Thanks for the reply.
I have read the paper above. I would like to ask
1) Is 'Mobilizer coordinates (q)' means the parameters that we can tune in the Opensim GUI 'Coordinates' tap? eg. Shoulder flexion/ shoulder elevation.
2) How can I know the numerical/analytical relationship between the Euler angles(theta) and Mobilizer coordinates(q) (equation (18) of the paper) that the model developer define? Can I know it from the Opensim GUI? or Can I access it through Matlab?
Thanks!! =)
Regards,
Hilary
