Model Scaling, RSM and Maximum Marker Error
Posted: Tue Aug 06, 2024 8:58 am
Hello everyone,
I am using opensim for gait analysis (kinematic) with lower-limb amputees but I am facing a problem when scaling my model.
I get high errors but then visually checking the experimental and model markers it looks like the error should be really low. Does anyone have any suggestions on what to change? I am only weighting markers on anatomical landmarks for scaling and I have slightly moved the markers on the general model to account for the prosthesis (e.g., femoral condyles are moved outer compared to able body people).
Also is there a way to export the markers error?
Thanks so much!

Reported errors:
Frame at (t = 2.5): total squared error = 0.00967638, marker error: RMS = 0.0219959, max = 0.0488547 (L_MKNEE)
