model degrees-of-freedom ...

Dear OpenCap team,

In the future, will the possibility exist to contribute different models to the OpenCap system? It's probably not necessary to say this, but some people require models that have a lot of detail at the neck, or the lumbar spine, or the hands. Obviously it's probably not desirable to have 'one model to rule them all' because it would have hundreds of degrees-of-freedom. So will it be possible to contribute different models to the OpenCap system in the future?

Thanks again!

Matt

Hi Matt, Yes. We plan to have the option to select different models prior to starting a session.

It is pretty easy to use OpenCap with different models for now. You can download the data at the end, and you get all of the marker trajectories, so you could run scaling and inverse kinematics offline with a different model. The generic models and setup files that we use are here for reference (https://github.com/stanfordnmbl/opencap ... imPipeline)
