Dear Experts,
I'd like to know how to visualize the results of JRF analysis in each joint (e.g knee) as a vector.
something like this:

The following thread might help you in this:

Just make sure that the ground reaction forces are measured in the ground frame. Then, you can preview them in the GUI through File -> Preview Experimental Data ...

Hi Dimitar,
Glad to see your response.
In OpenSim 3.3, I modified the JRF.sto to a mot file (changing the headers and also the extension).
after loading an IK motion to the model, I associated the JRF.mot to it. all joint forces displayed in the zero ground. then I edited the motion objects and just checked the point force and added the proper points to point columns then the joint vectors displayed properly at each joint.

But in Opensim 4.1, It freezes a lot and the above-mentioned method doesn't work.

This error also appears even when I load JRF.mot as experimental data.

And this is my file.
Anything wrong with this file?
Your response would be greatly appreciated.
Cheers
