BTK has an api with Matlab and Python bindings. You should be able to find the function you were using in the Mokka gui and write a script utilizing it. I'd ask on their mailing list.

Thanks.

Thanks, those are helpful. I just saw the email conversation between you and Ton. We are searching for an exisiting open source and open platform tool that computes joint angles, rates, accelerations, and moments for a human in gait given marker and dual force plate data. Before we implement our own...

Thanks James, I've already been looking through those and haven't been able to find exactly what I'm looking for, so that's why I posted a question here. I was hoping for more precise pointers to the information I'm interested in.

Hi,

Where can I find details about how OpenSim computes joint angles and moments (if it does that)? I'm interested in knowing which methods are used in detail and the C++ API calls that use them. I'm having trouble finding that in google searches.

Thanks,

Jason
