Ground Reaction Moment Coordinates

Post by Ryoji Kiyama » Mon May 09, 2011 5:09 am

Hallo everyone,

I would like to convert C3D file for OpenSim.
I created motion file, but I can not convert ground reaction data.
I believe the origin of ground reaction moment is the center of pressure. Thus, the ground_torque_y of both leg during gait should be asymmetry.
I don't know why the ground_torque_y of Gait2354 is symmetry.

Thank you for you help.

Hi all,

If you use VICON motion capture systems,
please try our toolbox which directly converts VICON motion capture data(*.csv) into OpenSim inputs(*.trc and *.mot).
This is much easier and faster than converting C3D files.

Please refer to our project page: https://simtk.org/home/lee-son/
The toolbox v.1.4.1 is already available, but the user manual is now in preparation.
If you have any questions in using our toolbox, please contact us.
