Scaling with Matlab

[Carlo Tricarico]

Hello everybody,
I was trying to execute a scaling operation of a model using matlab. Since now I was able to create two objects by doing:
- SC = ScaleTool('Setup_scale.xml');
- I = SC.getModelScaler();
- II = SC.getMarkerPlacer();

Now I have read that, in order to obtain the results needed, it is necessary to use the command 'processModel(...)' but I really can understand what are the inputs I have to put inside it. Can anyone help me?

Thanks in advance

Hi Carlo,

In the doxygen, https://simtk.org/api_docs/opensim/api_ ... 1b85ed4ff2, you will find the inputs.

modelScaler.processModel(states, model, pathtoSubject, mass)

So you need to provide model states, the model, the path to where the subject's data is, and the subject mass.

model = Model(yourModelHere);
states = model.initSystem();

Cheers,

David

David,
your help has been tremendously helpful, I have to thank you a lot. Just one more thing: once I've done the same thing to the MarkerPlacer, the results will be shown in the directory I've put inside the inputs of the "processModel " command?

Thanks
