Hello, I have noticed that when I switch OpenSim version, for example from 4.4 to 4.5, and update a model, for example using the MATLAB API, I obtain a model with slightly different parameters. For example, if I run like this simple code on the RajagopalLaiUhlrich2023 model: import org.opensim.model...

Hello, I have a very similar issue with another function of OpenSim JAM, also taking the State at Stage Position as input.
DId you manage to solve the issue by any chance?
Thank you,

Hello Zakia,
if I remember correctly sometimes the accuracy value could cause that. I would try changing to something like
in the IK setup file.
I hope this helps,

Hello, I am using the OpenSim API in MATLAB to extract the triangle proximity used in OpenSim JAM ( https://github.com/opensim-jam-org/opensim-core ) (from Smith2018ArticularContactForce) using a method called 'getTargetTriangleProximity' that depends only on State realised at Position stage: clear;...

Hello, I was wondering if the muscle attachments described in the MAP publication (https://doi.org/10.1016/j.jbiomech.2016.10.021) are available somewhere for inspection. I have checked the link provided in the publication (https://github.com/mapclient-plugins/fieldworklowerlimb2sidegenerationstep) ...

Hi Nathan,
can you please follow up with me about the MATLAB tool via email?
Thank you,
Luca

Thank you Ayman, that works!
Based on my tests the method did not exists for OpenSim 3.3 but that is not an issue.
Best wishes,
Luca

Hello, I am trying to update some of my scripts so that they can run on OpenSim 4.x but I like the idea of keeping backward compatibility with OpenSim 3.3, which I still use sometimes. I was wondering if there is any method available from the MATLAB API that returns the OpenSim version being used. C...

are you referring to the OPENSIM_HOME variable? We do have a MATLAB version of the tool as well, although still unreleased. I can send you a copy if you are interested. It would be good to go to the bottom of this though. Can you maybe try reinstalling OpenSim 4.1 adding it to the path? Please insta...

Both me and my students can load and use the plugin with no issues. Nathan, do you have more than one installation of OpenSim installed by any chance? In that case you might have the path variables mixed up. A system path variable refers to where your operative system looks for the OpenSim libraries...
