scale question:Strange scaling results

[XinYu Liu]

Hello everyone!

I'm new to using opensim.I recently used vicon to collect wrist data and opensim to calculate joint angles.But the scaling results are strange, with large errors from the collected static data.The marker "bih1" does not change when the data is rotated.And the angle of wrist rotation is out of range.It looks like the back of the model's hand has switched places with the center of the hand.

I would like to know what part of the process is wrong and how to fix it.I'm using openism 4.4 and the wrist model is the one that comes with the software.I will provide my static and flexion data, marker points and scale settings.

Thank you for your help!

Best regards

Xinyu
