animating ground forces and muscle forces
Posted: Sun Apr 13, 2008 5:38 pm
Hi.
I have added my own muscle force data to a text delimited file for opensim to animate. However it doesnt seem to like both ground reaction force data and muscle force data in the same file (I would like to display both on the animation).
If I include both muscle forces and kinetics in the one motion file, the animation only shows kinetics. When i take the kinetic columns out of the file (and modify the header appropiately), only then does the motion animate muscle forces.
Not sure if anyone has actually tried this but it would be great to animate both from the motion file. Could it be an ordering thing? Is there a specific order that the motion file needs to adhere to (i.e. kinematics, then kinetics, then muscle data??) I have tried several combinations with no luck.
Cheers,
