thank you for your matlab code about Lower Extremity EMG-driven Modeling with Automated Adjustment of Geometry.I had run it and the program ran about 8 hours and got results, it's too long. I hope do something about EMG-driven modeling,but It's a new field for me,can you give me some advice about ho...

thank you

emg = detrend(emg);
emg = ZeroLagButtFiltfilt((1/Fs), [30,300], 2, 'bp', emg );
emg = abs(emg);
emg = zeroLagButtFiltfilt((1/Fs), 6, 2, 'lp', emg);
I think all those is get excitation u(t) not the activation a(t),I understand is right?

Does opensim have a function of converting the EMG signal into activation？If not, where can I find it?

thank you,i know it.

thank you ！，i am the first time used opensim in matlab,i don't how to put the joint angle to the state.can you tell me how to put the joint angle to the state?

I have the current joint config,what function of opensim i can used in matlab to get the muscle's the Fiber Length.thank you!
