MocoOutputTrackingGoal

[mohadeseh shafie]

Hi all,

I am getting the following error when using the MocoOutputTrackingGoal() function, I have installed the latest version of Moco and OpenSim. What is the cause?

MATLAB error: Unrecognized function or variable 'MocoOutputTrackingGoal'.

Thank you in advance.

Hi Mohadesh,

I just tested OpenSim 4.4 locally and was able to create a MocoOutputTrackingGoal. What version do you have installed?

Hi Nick,

I have three versions installed, but I used version 4.4 to link with MATLAB.

Hi Mohadesh,

The issue is that Moco 0.4 is at the top of your Windows PATH, which means that Matlab will find this version before OpenSim 4.4. If you remove that PATH entry, things should work as expected, although it might be worth trying to reinstall to double check.

Best,
Nick

Thanks Nick, my problem is solved.

Hi Nick,

By removing the path, a new problem has arisen, and Moco does not complete the solution, ending with the message: "EXIT: Restoration Failed!"

Hi Mohadesh,

That means that the problem failed, most likely because it couldn't meet the constraints. Try adding strong CoordinateActuators to all DOFs and see if that converges.

Hi Nick,

When the Moco path exists in Windows at the beginning, the Moco run succeeds, and I receive an error when running the MocoOutputTrackingGoal function. However, if the Moco path is removed, leaving only the OpenSIM 4.4 path, the Moco solution ends at the stage I sent the photo, and the solution is not completed. Nonetheless, the MocoOutputTrackingGoal function executes correctly. I have uninstalled and reinstalled multiple times, but unfortunately, the issue remains unresolved. Please guide me. Thank you.

In the above message, I mean the problem that is completely solved with Moco is a mocoTrack problem, and I test the MocoOutputTrackingGoal() function separately, and I have not entered it yet.
