Static optimization (activation)

Hi every one,
I am wandering respect to what the activation of the muscles (Static optimization results ) are normalized too? Is it correct to assume that they are normalize to a parameter which rap represents the MVC?
thank you in advance

Re: Forward kinematic

The Inverse Kinematics Tool should do this if you set the "report_marker_locations" flag to "true": <InverseKinematicsTool> <!--Directory used for writing results.--> <results_directory>./</results_directory> <!--Directory for input files--> <input_directory /> <!--Name of the model file (.osim) to...

Re: Forward kinematic

Thank you very much for your kindness.
I have just one more question, if I haven't the .trc file with the markers trajectories, is it possible to do that with just a .mot file instead?

Forward kinematic

Hi everyone,
I'm wondering if it possible from a .mot file to generate the markers trajectories of the model (a .trc file).
Anyone did this before?
Thank you in advance :) Anna

Static Optimization

Hi every one!
I'm trying using the Static Optimization tool but I always obtain the violation of a coordinate, wich is of the body connected to the ground. I can I handle this?
Thankyou

Inverse Dynamics with a .xml file

Hi everyone! I' trying to compute inverse dynamics using the cpp Api of opensim directly. As I did for the scaling tool (through the class Scaletool which accept as input the setupscaletool .xml file) I'd like to do the same with inverse dynamics but I can't find the right function that accepts an ....
