Inverse Kinematics Errors

Hi everyone, I am currently on a project using Gait2392 to study knee angles and moments. Something i am trying to wrao my head around is how IK is done and its errors. With scaling, I have managed to get errors under 0.015m but then IK errors end up being 0.40+ m. Is this simply due to soft tissue ...

Hi, I am new to OpenSim and assisting in running trials on lower limb gait. But I was wondering how OpenSim calculates the hip joint centre? I understand that the femoral reference frame is calculated using three rotations from the pelvic reference frame, but any idea where I could find the rotation...
