negative muscle activation !!!

[Arash Mohammadzadeh Gonabadi]

Hi everyone,

I have a question about muscle activation.
I run Rajagopal2015 model in OpenSim 4.0 (GUI) and got negative activations for rect_fem_r and vas_med_r. Why are they negative?
By any chance can someone help me in this concern?

Thank you so much in advance.

best,

Hello all,

I have fixed the issue.
I just change "min_control" and "minimum_activation" from 0.01 to 0.0.
So we do not have any negative activation.
