Introductory OpenSim Tutorial at GCMAS 2015

This practical 2-hour tutorial will introduce participants to OpenSim's features, file formats, and documentation using clinically relevant examples.

I downloaded OpenSim - NOW WHAT?

This introductory tutorial at the 2015 Gait and Clinical Movement Analysis Society (GCMAS) annual meeting provides hands-on lessons for getting started with OpenSim.


GCMAS attendees (scientists, clinicians, and students) who are curious about the capabilities of OpenSim, but who have not previously used the software.


  1. Identify components of a musculoskeletal model in OpenSim and in the model's XML file.
  2. Load a model in OpenSim and animate it using measured joint angles and/or marker trajectories.
  3. Use an OpenSim model to examine whether muscle force- or moment-generating capacity changes substantially following a simulated surgery.
  4. Describe the steps needed to process motion capture and GRF data for input into OpenSim.
  5. List three limitations of existing OpenSim tools and three features to watch for in upcoming releases.
  6. Locate OpenSim online resources, documentation and examples for further exploration.
