Hi,
Thank you for your very fast answer! Would I use this script in MatLab then?
How do I find the coordinates in the frame that I want to use the force? I know where it is visually from a photo of our test subjects, but how do I know which coordinates it is and that I am in the correct frame?

Hi,
How do I choose the right frequency for filtering the movement in for example Inverse Dynamics? Is filtering needed if I have made up data with no noise?

Hi, I am working with a neck model, and I want to add an external load as a point force. We have an experiment where our test subject is pushing their head back against a resistance, and I want to simulate that to see what happens in my model, although I have no data for the force yet. Preferably vi...

I have the same problem, but I want to add a resistance when the head tilts back. I have looked in the tutorial and the files, but I still don't understand how to add that new element to the model. Is there anywhere where you can see how to do that without a pre-existing file?
