RE: *.trc files

Can I send you a *.mot file for inspection? The GRF in the animation seems to look ok. However, the moments for walking do not compare to the literature.

RE: *.trc files

<t>We have scaled data and can now run through the IK tool. Something is incorrect now with our forces and matching of these forces to calculate inverse dynamics. We have developed some matlab code to generate a similar *.mot file that contains our ground reaction forces. However our moments are qui...

*.trc files

I think a flow sheet would be helpful for motion capture users and what fields in the software to make this software work.

We attempted to take you full body example *.trc files and replace it with our data with no success. I am at a loss of what to try next.

marker set details again

We collected some motion capture data with a similar marker set. It seems we can scale the data with body weight and using a neutral trial. When loading the dynamic trial, the program crashes.

Is there any step by step process that you can provide for motion capture groups?

FAQ Marker Set and Force Platform Data

<t>We do mostly human movement work and find it hard to utilize opensim without further details regarding the format of the motion capture and force platform data.<br/> <br/> After looking into your *.trc files in the gait model, we are wondering if all markers in this model must be tracked? Can one...
