Hi James,

My ground reaction forces have units of Nm.

However, the marker trajectory data in my .trc files is in m whereas I've noticed Gait2354 and Gait2392 both have marker data in terms of mm. Could this unit difference cause any issues in the subsequent steps of OpenSim?

Thanks again,
Paige

Hi Qiu, Did you ever figure out what was causing such large force values? I'm having a similar issue, only my reported force values are too low (looking at the knee joint). I believe my experimental data units are correct. I have some differences in my setup file. I use states results from CMC and d...

Hi All, I’m working on a project that uses MotionMonitor as our motion capture software. The version we have is not capable of giving us C3D files so we have created a set of MatLab functions that write the .mot and .trc files for inverse kinematics and well as the ground reaction force .mot file fo...
