[Feature Request] track free moment and center of pressure in `MocoContactTrackingGoal` #3900

Closed mrrezaie closed 2 months ago

mrrezaie commented 2 months ago

Hi, I'm writing to ask for a new option in MocoContactTrackingGoal. If I understand correctly, the goal doesn't take account of free moment and center of pressure data. In my simulations, the forces are tracked really well, but I see significant deviations in other components: graph_grf

Given that the force plate data are probably the most reliable and accurate measurements among the experimental data, and that an inaccurate center of pressure could propagate errors to the proximal joints, it would be great to have this option in the MocoContactTrackingGoal to whether or not track the other components.

Thank you in advance.

@mrrezaie, this is on our TODO list and we already have an issue open for it: https://github.com/opensim-org/opensim-core/issues/3688.

Closing since duplicate.
