Re: Model question: extended Rajagopal with ligaments
Hello Christopher, I am not 100% sure there is a model out there that attempts to model each joint with the level of detail you are describing. Researchers typically increase the complexity based on the research question. So if you are interested in the small movements between the patella and the fe...

Re: Python Script to Transform Point from Rigid Body Frame to Ground Frame
Hello Max!
Are the angular coordinates in 'MyMotion.mot' in radians? They are expected to be in radians. Get and print the values of the states after you have set them for a given time point to ensure you have set them accordingly.
Thanks,
Nicos

Re: Python Script to Transform Point from Rigid Body Frame to Ground Frame
Hello Maximillian, Have you tried: findStationLocationInGround https://simtk.org/api_docs/opensim/api_docs/classOpenSim_1_1Frame.html#a84130c33892299d222d753c727289274 You need to first get the frame object for which your point is locally expressed in. That should do the trick. Best wishes, Nicos

Re: Assistance Required with Integrating Open-Source Datasets in OpenSim
Hello Elton, Did you take a look at the first link I shared in my previous comment? If you look at the section titled 'Reading C3D files through Matlab' it provides a code snippet for reading a *.c3d file and then converting it to the relevant files for usage with OpenSim (trc and mot). [1] Open-sou...

Re: Assistance Required with Integrating Open-Source Datasets in OpenSim
Hello Elton, Have you tried using the methods for converting C3D files to *.trc/*.mot files built into OpenSim? https://opensimconfluence.atlassian.net/wiki/spaces/OpenSim/pages/53090837/C3D+.c3d+Files Other available packages to do so can be found here: https://opensimconfluence.atlassian.net/wiki/...

Re: calcAngularMomentum() functionality
Hello Anushka, For each frame of your walking data you need to set each of your model's coordinates positions [1] and speeds [2] using your IK data. As an example: model.getCoordinateSet.get('coordinate_X').setValue(state,position_data(frame_i, coordinate_X_index); model.getCoordinateSet.get('coordi...

Re: Calculate the transformation matrices in a specific pose using MATLAB
Hey Rodrigo! Hope you are well! After you have set the relevant state information and realized to the necessary stage you can extract the Transform as follows: bodySet = model.getBodySet(); body1 = bodySet.get('your_body'); body1Transform = body1.getTransformInGround(state); if you then want the rot...

Re: Handling Data from 5 Force Plates
Hey Ali,
It looks to me as though you haven't updated the number of columns to reflect 5 force plates worth of data... it is currently at nColumns=19... time + 2*9 force plate signals... I think in your case it should be time + 5*9 - so 46.
Hope that helps.
