IMU Placer to IMU IK Clarification

Hi all,
I'm just looking for some clarification on how each IMU's orientation offset, as determined through the IMU placer, is used when running IMU IK. How are these offsets applied to collected orientation data / where and what in the source code completes this process?

Thanks,
Vincent

Manual scaling and computation of segment scaling factors

Hi everyone, I'm currently working on an inverse kinematics project with the skeletal version of the Rajagopal2015 model and do not have access to marker tracking for the purposes of scaling. I understand that I can manually input scale factors through the scaling tool. However, in order to manually...

Inverse Dynamics GRM Input

Hi! I'm new to using the OpenSim inverse dynamics functionality and am a bit confused on how GRM is defined as an input to ID. Is the GRM a function of the radius between the foot's CoP and the ankle or the foot's CoP and the body's center of mass?

Thank you!
