General information

The GAMMA (Gesellschaft für die Analyse Menschlicher Motorik in ihrer klinischen Anwendung, society focus on the clinical applications of 3D gait analysis. During this workshop the participants will learn how to use the OpenSim GUI for a typical data processing workflow. This workshop follows a similar workflow and uses the same example data as a previous OpenSim workshop (

Preparing for the workshop

Participants should bring a laptop with OpenSim 4.0 installed or be prepared to team up with other participants. OpenSim model files and setup files are written in xml. Notepad++ is a free text editor that makes it easier to view and edit xml files.  During the workshop we will use Notepad++ to examine OpenSim files. Hence, please download and install following software prior to the workshop.


Each point on the agenda will start with a short introduction talk from the organizers (5 to 10 minutes). Afterwards the participants can try to do each step on their laptop for approximately 20 minutes. The organizers will support the participants during the hands-on sessions.
To complete the tutorial please download data and setup files. For your reference, we also provide the output files.

Additional geometry files. Please copy this folder to your 'data and setup files' folder.

The slides from the Introductory talks to each topic can be downloaded with the following link: Slides
