 
| - Launch OpenSim and select Window > ScriptingShell to bring up the scripting window. This will display the main scripting shell window ("Jython Interactive Console") and the "Command History" of executed scripting commands.
- Select Scripts > Open... (Open > Browse for file... prior to OpenSim 3.1). Find the Scripts folder located in the directory where you installed OpenSim. There are many example scripts included with the OpenSim distribution. You can review these to get an idea of the capabilities of scripting or you can modify them to streamline the workflow of your own research.
- Choose "testVisuals.py". The script will open in the OpenSim GUI's file editor. This script demonstrates how you can control visualization via scripting. The script loads a model ("gait2392_simbody"), changes the color of the pelvis, makes the right femur transparent, and aligns the model view with the x axis.
- To run the script hit F5, with the script open. Alternately, you can choose Scripts > Run Current Script.
- Go to the Scripting Shell Window and review the Command History, on the right hand side of the window. This will show you all of the scripting commands that were executed. Review the commands that performed each of the actions in the testVisuals script.
- Try executing another script command to change the opacity or color of the pelvis. Enter the commands at the prompt >>>. You can copy and paste lines of code to test individual commands.
- Try doing the same thing by modifying the testVisuals.py script. Find the "Scripts" folder in your OpenSim Install directory, open the file with a text editor (e.g. Notepad++), and add the command. Save the script with a new name (e.g. myTestVisuals.py). Return to OpenSim and try out the new script. You can run the script directly by selecting Scripts -> Run... and navigating to your script. Does it perform the function you expect?
- Now try running, reviewing, and modifying the other example scripts included with your OpenSim distribution. The full list is below.
