Re: emg and marker tracking

thank you so much,
another scenario I am dealing with is that I i have a reference motion that is corresponding to 1.45m/s with 1s gait cycle duration and I want to use that as a reference to generate 1.1m/s gait with 1.15s cycle duration. I was wondering how I can handle that

emg and marker tracking

hello i am trying to track emg and markers at the same time i wonder if there is a way to assign different initial and final time for each reference file i.e. the maker set data and emg data as my emg data is processed and start from 0 to 1 s and the marker data i am going to use represent a stride ...

Re: Constrain Center of Mass to Follow Projectile motion

Hi everyone, Awesome discussion here! All of the above points are great. Regarding a MocoGoal for tracking projectile motion: what you'd need would be a MocoOutputTrackingGoal. We already have a MocoOutputGoal, which allows you to minimize any OpenSim Model output value. OpenSim Models provide an o...

Re: not accurate results from Moco Track

Hello,
Thank you for your reply,
I am going to get the inverse solution based on the markers and use the resultant joint coordinates to track and will tell you the results
thank you

Re: not accurate results from Moco Track

Hi,
The external forces are ground reaction forces from Vicon.
for the perturbation I prescribed the platform motion based on experimental data ( the prescribed motion is compatible with the data i want to track)

Re: not accurate results from Moco Track

one other thing I wanted to mention is that. the model is scaled and the platform motion is prescribed using an older version of OpenSim (4.1).
however, I don't know if it's something important

Re: not accurate results from Moco Track

Hi Nick, Thank you so much for your time and help. yes I'm sure that is not locked. I used the same everything only different versions of moco. As i told you before when i simulate it with newer version it takes very little time to give me the results which i think the reason is it doesnt solve it a...

Re: not accurate results from Moco Track

Hi , thanks again for your help and time. So I included two plot please also take a look at the other one that i compared same code solved by different versions so when I mentioned track only I commented out other goals. it is just tracking and i think the weight of the tracking doesn't make any dif...
