jar library is located by adding the path to the. To allow MATLAB to use OpenSim's Java library, the configureOpenSim.m file tells MATLAB where this.

OpenSim's Java library is located in the file org-opensim-modeling.jar in the OpenSim installation.

OpenSim has a Java interface/library (used by the GUI), allowing us to leverage MATLAB's Java capabilities to provide a MATLAB interface to OpenSim. MATLAB allows one to load and use Java libraries.

The code blocks below demonstrate how to read and write vector and scalar (double) data from and to a file. Reading from and writing to files has been improved with the introduction of tables and file adapters (available as of OpenSim 4.0). WiringInputsAndOutputsWithTableReporter.mĬreate a Reporter and wire the Inputs and Outputs necessary to report the system's center of mass. If no input model names are given, the user is prompted to choose a model to scale and all muscle strengths are doubled. Takes 3 inputs: 1) the path and name of an existing OpenSim model, 2) the path and name of the new model to be outputted, and 3) the scale factor. Run a simple optimization to find the elbow flexion angle where the moment arm of the biceps femoris short head is maximized.įunctionthat loads a model and itsmuscles,then creates a new model where all muscles are scaled by a common scale factor. SimpleOptimizerExample.m simpleOptimizerObjectiveFunction.m To see the results, load the model and IK output in the GUI. User must specify the results directory (e.g. Run multiple inverse kinematics trials for the model Subject01 located in the subfolder "testData/subject01". You must run setupAndRunIKBatchExample first to generate the motion files used in this example. Generate OpenSim Setup Files for the Analyze>MuscleAnalysis tool and runs the Analyze tool.

It uses a helper function defined in the script createPrescribedMotionModel.

Generate a simple tug of war model, run a simulation, and visualize the results.Ĭreate an OpenSim model with coordinates prescribed according to an input motion file. OpenSimCreateTugOfWarModel.m TugOfWar_CompleteRunVisualize.m Load a C3D file into OpenSim Tables and write out the marker and force data to corresponding.

Test that everything is configured correctly: In the command window, run the following:.

Restart MATLAB the OpenSim libraries will not be recognized until doing so.

Or see here for additional help on setting your PATH environment variable. The steps to set your path are shown in the animated image below.

Windows users: ensure that the OPENSIM_INSTALL_DIR/bin directory (e.g., C:/OpenSim 4.0/bin) appears in your system PATH environment variable, and that it appears before any other OpenSim installations you may have on your PATH.

If the script did not succeed, read the output in the command window for more information.

When the script finishes, you should see a dialog box notifying you if the script succeeded.On Windows, by default, this is C:/OpenSim 4.0. The script will prompt you to choose your OpenSim installation directory (we will refer to this as OPENSIM_INSTALL_DIR). Run the configureOpenSim.m file from the current folder.On Windows, by default, this is C:/Users//Documents/OpenSim/4.0/Code/Matlab. Change your Current Folder to the OpenSim Matlab Scripts directory.If you're using Windows and you have OpenSim 3.x configured with Matlab, make sure to "Run as administrator" (available by right-clicking the MATLAB application in the start menu, etc.). As noted above, OpenSim 4.0 requires 64-bit Matlab. These instructions assume that you've already installed OpenSim version 4.0 or later (see Installation Guide for more info).
