Error using IDAnalysis

In this project, we developed a MATLAB-based framework for OpenSim to calculate muscle activations and forces that also satisfy mechanical stability requirements.

Error using IDAnalysis

Post by Mojtaba Safari » Mon Mar 22, 2021 1:21 pm

Hello Mr. Akhavanfar,

I studied your research about Development of a novel MATLAB-based framework for... and I would like to use your MATLAB code in my project
but when I run your code with your default setting I get the following error :

Error using IDAnalysis (line 28)
Java exception occurred:
java.io.IOException: InverseDynamicsTool Failed, please see messages window for details...

at org.opensim.modeling.opensimModelJNI.InverseDynamicsTool_run(Native Method)

at org.opensim.modeling.InverseDynamicsTool.run(InverseDynamicsTool.java:117)


Error in Main (line 74)
ID= IDAnalysis(ModelFilePath,ModelFileName,AnalyzeFilePath,AnalyzeFileName,MotionFilePath,MotionFileName,initial_time,final_time,extLoadsXml);

I have successfully configured OpenSim with Matlab such as Environment setting in Windows and path setting in Matlab so I don't know what is wrong

if possible please guide me
Thank in advance

Hello Mojtaba,

It's probably because you didn't change the directory path in the xml file setup or you put a wrong directory in the first lines of the main file.

Please open External_Load.xml. Then, in the <datafile> section, copy and paste the right directory in your computer. Attached is the pic of that section based on where I saved the folder in my laptop.
