How to Use the CMC Tool

How to Use the GUI

The computed muscle control tool is accessed by selecting Tools → Computed Muscle Control… from the OpenSim main menu bar (figure below). Like all tools, the operations performed by the computed muscle control tool apply to the current model. The name of the current model is shown in bold in the Navigator. See chapters Opening, Closing, and Using the Navigator Window for information on opening models and making a particular model current.

The Computed Muscle Control (CMC) Tool is controlled by a window with three tabbed panes (figure below). This window is the same as that used for RRA (see Residual Reduction Algorithm).

  • The Main Settings pane is used to specify parameters related to the input kinematics of the current model, the time range for the analysis, and the output of the results.

  • The Actuators and External Loads pane is used to specify additional actuators, such as residual and reserve actuators.

  • The external loads and integrator settings are specified in the same manner as in Forward Dynamics.

Command-line Execution

CMC is run using the command cmcgait -S <setup file> where <setup file> is the name of the setup file, for example, 

cmcgait -S subject01_Setup_CMC.xml
