In the image below I have the gait lab data of a foot which is simulated in opensim giving out joint angles with respect to time. https://ibb.co/NSQPScZ - Image is here. To get out the angles of the foot a marker was placed on it. Is there a way to output the position of the foot too as it moves thr...

The force data I obtained via a mot file which was obtained from the gait lab and translated into opensim. No external forces/loads were applied.

With respect to your answer of ground reaction forces, would that just not be x% multiplied by the body weight of the individual? So I need to find the weight of one muscle group(s) in order to get out a round reaction force?

So is there no way to find out the overall force produced from one leg/foot?

So I have managed to do the inverse kinematics. However I am still struggling with the inverse dynamics. I have got an inverse dynamics file and all i want to find out are forces using opensim. Any further help you can give?

Thanks.
