1. In the OpenSim GUI, select File>Open Model....

2. Navigate to your OpenSim resources directory and find the Models/gait10dof18muscGait10dof18musc directory.

3. Select subject01_metabolics.osim. This is the final model created in the RRA step described above, with metabolic probes/calculators included. The OpenSim GUI will now show a view window containing a model with a skeleton.
4. Go to the Navigator panel and use the + icon to expand the list of components in the model. From here, you can explore the bodies, joints, and forces (i.e., muscles) that make up this model.
5. Go to the Coordinates panel, which lists the degrees of freedom in the model. Move the sliders to change the values of the coordinates.
6. Try changing the model view in the Visualizer Window to zoom in on the ankle joint (see Navigating the Visualizer Window).
7. Compare the RRA model (which you just loaded) to the generic model:
   
   1. Reset the scaled model (walk_subject01) to its default pose by going to the Coordinates panel and selecting Poses>Default. Zoom out to bring the full model into view. You can use the box icons in the top-left corner of the Visualizer Window to center the camera on the X-, Y-, or Z-axis. (See Navigating the Visualizer Window for more tips.)
   2. Open the generic model by selecting File>Open Model..., navigating to Models/gait10dof18muscGait10dof18musc, then selecting gait10dof18musc.osim. This newly loaded model is now the Current Model, with its name shown in bold in the Navigator panel.
   3. Compare the mass of the torso segment between the two models. Highlight the body of interest in the Navigator panel, then find the mass property in the Properties window.
   4. Compare the model sizes in the Visualizer Window.
   5. When finished, close the generic model by right-clicking the model's name in the Navigator panel and selecting Close from the drop-down menu.
