Hi guys

In this code, the joint angle in opensim is degree or radian?

state = HGait.initSystem();

Coordiantes = HGait.getCoordinateSet();

Coordiantes.get('ankle_angle_r').setValue(state,tar)

Do you think I should set the joint angle in degrees or radian?

Hi,

At the low level API calls in your code snippet, the angles are always in radians (for rotational motion type). Conversion to/from radians to degrees is used exclusively for application/end-user facing functionality.

Hope this helps,
