Research Grade Upper Extremity Model for OpenSim?

Hello,

I am trying to use OpenSim to calculate upper extremity joint angles (bilateral Wrist, Elbow, Shoulder, Trunk) from IMU data collected. I have looked through the library of musculoskeletal models on the OpenSim website, but I cannot seem to find one that is research grade and has segments for all these upper extremity segments.

The Upper Extremity Dynamic Model (https://simtk-confluence.stanford.edu:8 ... ht%20upper) appears to be what I am looking for, but when I load it into OpenSim 4.4 there are mirror errors which display leaving me with only the right side.

Is there a model that you are aware of that will satisfy my needs? Or do you have a solution for the error I am receiving for the model listed above?

Thank you
