Kinetic analysis withMTP = False and errors

[Jade He]

Hi All,

My goal is to improve walking JRA results (i.e., KAM). I am trying to take the approach of welding the MTP joint. I thought I could do so by "settings['withMTP'] = False." And then I got error messages (attached).

My questions are:
- Is welding the MTP joint an appropriate approach to improve JRA results for OpenCap?
- Are the error messages related to Force? getting force to applied to the foot?

Thank you for your input/thoughts in advance!

Hi,

I think that's an old feature that is no longer supported I will open an issue to fix that. I doubt you would get better results with no MTP. I added the MTP after finding that it gave me better simulations: https://journals.plos.org/plosone/artic ... ne.0256311
