MOcap model wrong Knee flexion generated

I have used my own c3d data to perform human gait analysis in mocap model.
Earlier all the ROM moment profiles were following the literature values but when i attached an exolink on right leg only for some studies and later removed it, I observed a change in sign of x axis data.

And when i checked this with default mocap model, the same changes are observed there also.

Please guide me on how to resolve this problem

Hi

It sounds as you un-intentionally has made a change to the body model? since the mocap model is now also changed.

If so replace the modified files.

Best regards
