Curious about more analysis by OpenSense

I understand I can do inverse kinematics on IMU data from OpenSense, but is it possible for me to do further analysis such as RRA, CMC just like the motion capture data?

Thanks for your question. We have merged the OpenSense functionality, including some updates and big fixes, into the 4.1 release of OpenSim. We ask that you use this version of the software going forward. Our documentation is here:

We also ask that you post any OpenSense related questions on the OpenSim forum:

To answer your question, you could do other analyses once you compute joint angles; however, other tools like CMC and RRA often require that you have measured ground reaction forces, as well. It may also be necessary to scale your model to get accurate results. The IMU data alone might be sufficient to study upper extremity movements (e.g., reaching), but the results would need careful validation.
