Analyze Tool Exception

[Pierre PUCHAUD]

Hi,

I'm trying to launch the analyze tool from Matlab on a new model I built. I only want to compute the moment arm from an inverse kinematic file "_ik.mot".
So i wrote the following xml file :

Code: Select all

Here is what I get in the matlab command window:

Code: Select all

Exception in analyze: ModelComponent::getModel(): component does not belong to a model. 

I don't understand what kind of component does not belong to my model ?

Plus, when i simply try to run the analyze tool in OpenSim, I don't get any value in the sto file.

Any suggestion would be appreciated.

Best regards,

Pierre.

Hi There

You need a controls file. The controls file is a CMC result file.

Check out the "How to use" page:

I hope this helps.

Hello Julian,

Thank you for your reply.

I saw it in the Tutorial page that they use a CMC result to compute special features. Since I don't have any force plates involved in my trial, I can't perform CMC. Moreover, I think moment arms are more or less a geometrical problem so inverse kinematic data should be enough to compute it, Am I right ?


Best regards,

Pierre.

I've found my mistake to run the analyze tool.

I finally added external forces .mot and runned inverse dynamics.

Plus, I removed this part of the .xml setup file of analyze.

Code: Select all

<ControllerSet name="Controllers">
         <objects>
            <ControlSetController>
               <objects/>
               <groups/>
            </ControlSetController>
         </objects>
      </ControllerSet>

Best regards,
