muscle controls not working in analyze tool

[Josh Baxter]

is it possible to analyze muscle contraction dynamics through some prescribed motion and prescribed muscle control?

i've tried using the analyze tool and provided both a muscle controls file and a motion file. however, the muscle excitations just stay at their default values and don't change as prescribed by the controls file.

Hello,
We are using OpenSim 4.3 and are having some difficulty with the Analyze tool. We have controls for states based on EMG and have motion files, but OpenSim isn't calculating the excitation states. Any thoughts or suggestions would be much appreciated!
Thanks,
Laura
