Thank you for your reply. I am analyzing ground level running for a healthy adult. Yes, I change mass of each segment after each RRA iteration. Also, I have put weights on tasks I want to track closely and have gone through the RRA troubleshooting and best practices, but all in vain. The optimal for...

Hello Vishal, I have been trying to understand working of RRA and how to optimize the weights to reduce residuals. So far I have not had much luck. I went through your post and thought you might have gotten a better understanding of RRA now. After running RRA for several iterations the pelvic moment...

Hello, I am trying to extract TRC data from a static trial that does not have force data, using the matlab code "osimC3D.m". But it seems in order to run this code successfully, data from force plate should also be present. Can anyone here help me or suggest a way to extract TRC data from C3D files ...

Hello Tom, Thank you for your reply. There are few things I do not understand which needs to be done after scaling the model. For instance, in the paper by Ajay et al it say "The remaining parameters were determined by minimizing the squared errors between model and subject marker locations from nin...

Also if anyone has got it successfully done can you please sharing the scaling factors, so that I may get the idea. Sorry but I ...

Hi,
I was wondering whether I can incorporate fatigue using MATLAB into OpenSim models. I understand I can do this through C++ but I wanted to try it on MATLAB because I am not that efficient at C++.
Any suggestions would be greatly appreciated.

Thank you Thomas for your suggestions.
But can I achieve this directly with MATLAB, without creating a plugin?

Hi, I wanted to add fatigue to muscles using Fatigable Muscle class through a MATLAB code. When I try to access the FatigableMuscle() in MATLAB, it throws an error saying no such class found. I suspect this is due to MATLAB's limited access to OpenSim's library. Has anyone here tried to incorporate ...
