Re: Setting Up Mimic Measure

Hi Thomas, Sorry to jump in here, and thank you for the great software. I'm hoping to use SCONE to optimize muscle activation to track a reference motion(stored as a .sto motion file that can be loaded in OpenSim as a motion) over a period of time as closely as possible subject to muscle parameter/l...

Re: MocoTrack Failed: Invalid_Number_Detected

Hi Nicholas, Thank you for your reply. I have experimented with the default guess, and the randomization is only my attempt to debug the issue after many failures with the default "bounds" guess. I will try visualizing the muscle/model state using the default initial guesses, which I believe is the ...

MocoTrack Failed: Invalid_Number_Detected

Hi, Thanks for the great project. I'm trying to use MocoTrack with a marker trajectory .trc file that I collected myself and solve for the muscle activations that tracks the trajectory. However, after following the tutorial and examples, I'm having a hard time getting the solver to converge. It woul...
