MocoTrack solving with unrealistic motion

Hi all, I am working on tracking experimental walking and predicting changes to kinematics when muscles are weakened unilaterally. I started by working with the weakened abductors condition code from the Moco paper and got good results when I changed the code to weaken muscles on only one side, but ...

Re: Choosing Moco weights and constraints

Thanks Nick! This is helpful. Yes, I am using a foot-ground contact model. I already have constraints on the initial position of the trunk and pelvis based on the reference kinematics, would you recommend setting more initial joint speeds and values to compensate for losing the symmetry? Or is there...

Choosing Moco weights and constraints

Hi all, I am working on simulating walking with MocoTrack and have a couple of questions. First, I am hoping to look at the effect of unilateral muscle weakness on kinematics but have only had success getting Moco to solve with a symmetry constraint. Otherwise, I exceed maximum iterations or will ge...

Re: MocoTrack will not initialize

Thanks for the quick response!

I am using OpenSim 4.5 and running Python in VS Code via Anaconda. I am able to get other files to run including the Moco Track and Moco Inverse example codes included in the OpenSim download.

MocoTrack will not initialize

Hi! I am learning to work with Moco and trying to run MocoTrack based on the tracking_walking.py file from the paper code. I started with the code in the folder and then changed the types of tracking scenarios I'd like to run, and tried to change little else about the code other than to not include ...
