Thank you for your answer Dimitar Stanev. First of all, there was a typo in the post. (state, aCoord) instead of (state.aCoord). My opensim model has only one degree of freedom in each joint, so it was the purpose of the code first to see how much moment arm the bifemlh_r muscle has for generalized ...

Hello. I'm working on a task to get the 'net joint torques' of the generalized coordinates by using opensim API with MATLAB. Specifically, given the states(i.e. angles, angular velocities, muscle lengths and muscle actuations) and controls(muscle excitations) in my model, I want to calculate the net...

It seems like to use 'CMC Tool' to compute exact muscle activation from the attached states file.
I could get all muscle actuation values between 0 and 1 by using CMC Tool.
Thanks.

Dimitar Stanev,

Attached is my result file for the simulation.
8, 9, 11 ... columns are muscle activation.

Thank you for your comment.

Hello, I'm using Opensim 4.0 and working with Lowerlimb model that has 3DOF(hip, knee, ankle) and 9 muscles. When I hit the 'simulate' button from default model poses, the opensim generates 'Results' file that consists of angles, velocities, fiber length, and muscle activation. The muscle activation...
