Re: Processing taking a very long time

Hello,

I'm experiencing a very long processing delay. Last week, it was a matter of a couple of minutes, but today, it has been more than 12 hours since the upload.

What are the best time windows to run OpenCap to avoid these big delays or long queues?

Best regards.

Re: Tests for the children with abnormal gait patterns

Hi Xiaoxia and Matt, I thought I could help on this subject here since I will be starting a very similar project too. As Matt said, in OpenSim, the IK relies on weights to "trust" the markers' data. More weight equals more "trust." I regularly process mocap data (Vicon) with OpenSim. If the patient ...

Re: segment power analysis

Hello Nick, Let's give it a try, for sure! I'm currently in "writing mode" , so I will get back to this soon (I hope). And don't worry. I just can say "Thank you Moco Team" for all that you guys had been doing. It is the main tool for my research, and as years went by, each new version solved someth...

Re: segment power analysis

Hello Nick and everyone. I saw that the OpenSim 4.5 had enhancements in Moco as well. https://simtk-confluence.stanford.edu:8443/pages/viewpage.action?pageId=130187315 The utility function createExternalLoadsTableForGait() now outputs center of pressure locations for foot-ground contact force elemen...

Re: Same code, different solutions on different computers?

Hello Pasha! Your post remembered this old one: https://simtk.org/plugins/phpBB/viewtopicPhpbb.php?f=1815&t=16529&p=45808&start=0&view= From the little that I know, IPOPT has some randomness in its operation with guesses, as Ross mentioned here https://simtk.org/plugins/phpBB/viewtopicPhpbb.php?f=18...

Re: Unexpected interruption of optimization iterations

I think I got the same problem in a simple simulation of isometric max torque. Restoration phase converged to a feasible point that is unacceptable to the filter for the original problem. Restoration phase in the restoration phase failed. I had never seen this before. I will try different guess file...

Re: Moco goals for average speed in cycling model

Yes Ana, that was the idea of the test... But the behavior that you are observing is interesting.

If it helps, I generally start with the Pattern Info, and then I set a state differently, usually setting all the parameters (range, start, end).

I will start checking this in my simulations also :lol:

Re: Moco goals for average speed in cycling model

Hello Ana, It might be worth checking out if there is a difference when you set the overall coordinate's speed as below. problem.setStateInfoPattern('/jointset/.*/speed', [-50, 50], 0) It usually works for me. Checking the Moco output for every little bit of state and control is always a good proced...

Re: Moco goals for average speed in cycling model

Hello Ana and everyone, Ana, what I mentioned about MocoOutputGoal and MocoOutputFinalGoal are messages from my future self to a current version in multiverse. I already took my suffering figuring it out myself. When using MocoOutputFinalGoal, the cost is measured in the final So it is good if you w...

Re: Moco goals for average speed in cycling model

Hello Ana and Aaron, hello everyone. I could add some thoughts to the question; maybe it will lead to a good discussion and test. From my experience, there are options in tracking and prediction scenarios: Tracking goals: MocoStateTrackingGoal & MocoAngularVelocityTrackingGoal Since they were design...
