Below is a list of available packages made available by members of the OpenSim community to convert experimental data into OpenSim format. In using these utilities, we ask that you respect the hard work of your fellow researchers by citing their work appropriately. Please carefully review the publications and cite the references in your future papers and presentations. No guarantees about quality, correctness or support are provided by the SimTK team or OpenSim team. Use at your own risk. Please consider contributing. If you would like to have your project included on this site, please contact opensim@stanford.edu.
| Package | Brief Description | Platform | Authors | License | Included Materials | Last Updated | |
|---|---|---|---|---|---|---|---|
| OpenSim 4.0 |  | OpenSim 4.0 has incorporated methods for reading C3D data via the API. Further information can be found on the C3D (.c3d) Files page. | Matlab, Python, GUI Shell | OpenSim Team | Custom | Online documentation and utility scripts. | Ongoing |
| MOtoNMS |  | MOtoNMS is a Matlab toolbox able to read motion data stored in C3D files and process markers trajectories, ground reaction forces, and EMG signals for OpenSim and CEINMS. | Matlab | Alice, Mantoan, Monica Reggiani | GNU General Public License | Extensive online documentation, example data | Ongoing |
| GaitExtractToolbox171 |  | Matlab toolbox to assist in extracting kinematic, kinetic, and EMG information directly from a C3D file for use in OpenSim. The scripts can be configured for any laboratory configuration. | Matlab | Tim Dorn | MIT License | PDF Instructions and Example data | Jan, 2011 |
| Matlab_Opensim_Tools_v2 |  | Folder containing a number of functions for processing data from C3D files to OpenSim format and for generating setup files and running scale/ik/id from the matlab command line. | Matlab | Glen Lichtwark, Ayman Habib, Rod Barrett | MIT License | Readme instructions and example data | August, 2013 |
| OpenSMAC1.0 |  | This project contains a utility program (OpenSMAC) that converts motion files from a Motion Analysis Corp. system (TRB and ANB files) into a format supported by OpenSim (TRC/MOT). It can also convert C3D files if you have a valid license and hardware key for SIMM and the Motion Module. | Motion Labs C++ plugin | Peter Loan | Custom | PDF Instructions | Dec, 2009 |
| Lee-Son's Toolbox |  | This toolbox converts VICON motion capture data into OpenSim inputs. Converts data into *.trc (marker trajectories) and *.mot (force plate data) files. | Binary (.exe) files | Sangjun Lee and Jinkyou Son | MIT license | Manual, Example data | Sep, 2013 |
| A set of matlab scripts for preprocessing experimental data to put it in format expected by OpenSim. These scripts were developed by Ajay Seth to process C3D from Gillette Children's Specialty Healthcare. | Matlab | Ajay Seth | Custom | Aug, 2008 | ||
| A Matlab script, with examples, to generate GRF .mot files and an external loads setup file compatible with OpenSim 2.4. The script works with standard gait lab GRF data from pre-2.0. A README file with instructions is included with the download. | Matlab | Sam Hamner | Custom | Jan, 2012 | ||
| C3D Tools by BSN Labs |
| C3D Tools is freeware for exporting marker, analog, and forceplate data. Exports .trc and .mot files compatible with Opensim. | Standalone exe (Windows only) | Soroosh Bagheri | Custom | 2019 | |
| STO / TRC / MOT File Plotter |
| This Matlab tool allows the user to load up to 4 different files that use sto, trc and mot extensions. The user has the possibility to add a TAG name for each file and this TAG name will be used as legend to plot the selected data in the next window. The user can also extract ALL or only the desired data in a mat file. | Matlab | Emmanuel Ayad | Utility scripts | 2020 |
