Re: Compatibility issues between MacOS arm-64 and x86_64 versions

Hey, example_kinetics.py uses OpenSimAD to run dynamic simulations using OpenCap data: https://github.com/stanfordnmbl/opencap ... inetics.py. Hope it helps, Antoine

Re: Hardware requirements

The resolution is fixed at the app level, so it should not matter. We do observe lower overall quality with older models, so I would tend not to buy the oldest ones out there.

Hi Carlo,

OpenSimAD has no support for arm64. Will try to work on that soon. It should work on other platforms.

Best,
Antoine

Re: The type of motion data

Not out of the box, you can run dynamic simulations to get an estimate of ground reaction forces: https://github.com/stanfordnmbl/opencap-processing?tab=readme-ov-file#examples. See install instructions first https://github.com/stanfordnmbl/opencap-processing?tab=readme-ov-file#install-requirements ...

Re: Kinematic data

Hey, The marker weights generally depend on how much you "trust" these markers. The higher the more importance that marker has in the least-squares problem. Markers positioned on anatomical markers typically have higher weights. We run inverse kinematics to compute joint angles: https://github.com/s...

Re: 3D knee kinetic

Hey, It is tricky to get the OpenSimAD code to work with another model. You can get check here some work in progress to support one additional dof: https://github.com/stanfordnmbl/opencap-processing/pull/114/files What is especially tricky is how do want to actuate these extra degrees of freedom. It...

Re: Kinematic data

Hey, Do you mean IKCoordinateTasks during scaling? https://github.com/stanfordnmbl/opencap-core/blob/main/opensimPipeline/Scaling/Setup_scaling_RajagopalModified2016_withArms_KA.xml#L620-L729 If the subject cannot perform a neutral pose that meets the IKCoordinateTasks, then I would suggest to re-do...
