Hello, I am using Opensim 4.0 and trying to find the various kinematics of my head and neck model; specifically the joint angles. I am doing this using the "kinematics" analysis in the Forward Dynamics tool. I would like to know what the coordinate frame of the output file is i.e are the angles obta...

Hello, I am trying to hold the neck in the initial vertical position for a certain amount of time. I am going about this by providing a 1) motion (.mot) file, which is zeros in all columns of joint forces as that is the only way I can keep the head from dropping. 2) Input this motion file to inverse...
