Thank you! So this is the case even though the .sto file generated by Body Kinematics says: "Angular velocities and accelerations are given about the body-local axes." ?

I am using a full body opensim model (Hamner 2010) and am hoping to calculate whole body angular momentum with respect to the center of mass of the whole body. I see I can get segment positions, velocities, orientations, and angular velocities from the Body Kinematics tool, but I want to make sure I...
