There are five drop-down menus available from the OpenSim main menu bar:

The File drop-down menu includes the following options which allow you to input and output information about models and motions:

 

The Edit drop-down menu is used to modify the following:

The File Editor allows you to edit the properties of the .xml files used in OpenSim. OpenSim settings (.xml) files contain, for example, settings for tools or additional data for models including marker sets, actuator sets, or control values.

To open the file editor: 

  1. Click Edit → File (.osim, .xml)...

  2. In the window that appears, locate and select the file you wish to edit. 

  3. A File Property Editor window will open, listing all of the editable parameters, along with any corresponding descriptions, for that file. To change the value of a property, double click on the value, enter a new value, and press the Enter key. 

  4. To save the edited file when you are finished, click the Save button in the Property Editor window.

    Note that on Mac, the + sign in the Property Editor dialog is replaced with the collapsed/horizontal arrow.

The Preferences Editor allows you to change user preferences for the 3D View window and other parameters in the OpenSim GUI. To read about these properties described in detail visit the next section, User Preferences page.

The scripts menu gives you acces to a set of GUI scripts for model editing, batch processing and more. See the section on Scripting in the GUI for more details. A set of example scripts are included in OpenSim in the default Scripts directory.

  • Use Open -> to open a script in the GUI. The set of scripts displayed is populated from your Scripts directory, which is <OpenSim Install Directory>/Scripts by default. You can change this by modifying your User Preferences. You can also choose Browse.. to open a script that isn't in your Scripts directory.
  • Use Run -> to run a script in the GUI. Again, the set of scripts displayed is populated from your Scripts directory, which is <OpenSim Install Directory>/Scripts by default. You can change this by modifying your  User Preferences. You can also choose Browse.. to open a script that isn't in your Scripts directory.

The Tools menu enables you to easily perform the tasks needed to generate and analyze musculoskeletal simulations. The following tools are available in OpenSim:

  • For more information on the plot tool visit Plotting
  • For more information on scaling your model visit Scaling
  • For more information on the inverse kinematics tool visit Inverse Kinematics
  • For more information on the inverse dynamics tool visit Inverse Dynamics
  • For more information on the static optimization tool visit Static Optimization
  • For more information on residual reduction tool visit Residual Reduction
  • For more information on computing muscle control visit Computed Muscle Control
  • For more information on the forward dynamics tool visit Forward Dynamics
  • For more information on the analyze tool visit Analyses
  • The Convert Files option converts any model (.osim), storage (.sto) or setup files (.xml) to the latest versions supported by OpenSim.
  • For more information on plugins see Using Plugins

Note that the availability of these options depend on the current model you have in the application.

The Window menu controls what windows are displayed:

The Help menu includes the following options:

  • The Online Help option will direct you to a the online OpenSim support page that includes all the references to the OpenSim resources, plus a search box.
  • The User's Guide option will direct you to the online User's Guide on the OpenSim wiki page (Confluence). If you're not online, you will be taken to a local copy.
  • Under Examples & Tutorials, you can go to the online library of examples and tutorials or directly to one of the introductory tutorials. If you're not online, you will be taken to a local copy.
  • The XML Browser option launches a browser containing the XML tags for all OpenSim objects.
  • The Doxygen option (for advanced users) takes you to the OpenSim doxygen, describing the class structure and functions in the OpenSim API. If you're not online, you will be taken to a local copy.
  • The About option opens a window giving more details about the software and includes acknowledgements and references.
  • The Report Bug… and Request Feature… options will direct your default Internet browser to the Simtk.org website in order to report a bug or send a feature request to the OpenSim developers, respectively.
