The .sto File Format
The results of a SCONE simulation are stored in the STO File format, which is a row/column based format, in which the data type is stated in the column headers:
Channel Name | Data Type |
---|---|
time | Time [s] |
<dof> | Value of a specific Degree of Freedom during the simulation in [rad] or [m] |
<dof>_u | Derivative (speed) of a specific Degree of Freedom during the simulation in [rad/s] or [m/s] |
.activation | Current activation [0..1] of a muscle |
.fiber_length | Current length [m] of the contractile element of the muscle |
.fiber_length_norm | Current length of the contractile element of the muscle, normalized by optimal fiber length |
.fiber_velocity | Current lengthening velocity [m/s] of the contractile element of the muscle |
.fiber_velocity_norm | Current lengthening velocity of the contractile element of the muscle, normalized by optimal fiber length |
.excitation | Current excitation [0..1] of the muscle |
.F | Normalized contraction force [0..1] of a muscle |
.L | Normalized CE length of a muscle |
.V | Normalized contraction velocity of a muscle |
.com_pos_* | Center of Mass position [m] of a body |
.lin_vel_* | Linear velocity [m/s] of the Center of Mass of a body |
.ori_* | Global orientation of a body, stored as a rotation vector [rad] |
.ang_vel_* | Angular velocity [rad/s] of a body |
.load | Joint load [BW], normalized by weight, i.e. load = joint_force / ( model_mass * g ) |
