moment arm of path actuator during CMC

Dear All,
How to get the moment arm and moment of a path actuator during a CMC analysis? I tried using Muscle Analysis as suggested in the forum . But It did not work out. I mentioned the name of the path actuator in the <muscle_list>(i.e <muscle_list> Actuator_r<muscle_list>). I am not sure if this is correct When I did that I did not get the results. It gave a file only with time steps, nothing else. I use opensim 3.3.
Any suggestion will be highly appreciated.

Thanks & Regards,
Karthick.

You can access the PathActuator's GeometryPath (via Matlab or Python scripting) and use the computeMomentArm() method (https://simtk.org/api_docs/opensim/api_ ... 6fb26e24f3). Please see the Confluence documentation (e.g., https://simtk-confluence.stanford.edu/d ... /Scripting), your OpenSim installation directory, etc. for scripting examples.

Dear Thomas Uchida,
Thanks for your reply.
I could do as you suggested. But is there a way to get it during CMC similar to getting moment arm of muscles by adding a muscle analysis in the CMC setup file?
Thanks & Regards,
Karthick.
