Hi,
I am new in OpenSim. I want to get joint angle from joint position. Now I have collected joint position data using motion capture. I know I need to find a suitable model and define model markers firstly, but I don't konw how to do it. Can anyone give me some detail help ?

You need to decided on the model that you will use. Then attach the markers according to your setup, perform model scaling and finally inverse kinematics. Please go through the user guide and tutorials

I have viewed the website you offered. However, I'm still puzzled about it. Could you give me an example ?

A good place to start might be working through the three tutorials here: https://simtk-confluence.stanford.edu/d ... +Tutorials. There, you will also find examples that demonstrate using the OpenSim Tools.
