Hello, well I cannot tell from the links you sent but if you upload the .osim files properly, you should be able to double click on it on Colab and see the details properly on the right hand side. If this is not the case, you have not uploaded it properly. Another suggestion is that you download you...

Hi Fernando,

Thanks for your question. Could you share your piece of script that you try to load the model? In general the process should be quite similar to what we have shown in tutorials.

I think I got why there was no differences. I used the same stiffness and inputs from the example on ankle for the knee spring. I am just wondering now if RRA and ID can calculate (or consider) other actuators e.g. added torsional knee spring. I could not verify this yet. Finally, after I perform CM...

Hi all, I am using this example below to perform a muscle-driven simulation with a torsional knee spring using gait2392 or gait2354 core models: "Simulation-Based Design to Reduce Metabolic Cost" page ( https://simtk-confluence.stanford.edu:8443/display/OpenSim/Simulation-Based+Design+to+Reduce+Meta...

Dear all, I wonder if you could direct me to a procedure or a framework to evaluate e.g. a knee brace effect on joint biomechanics vs. no brace option in OpenSim. Let's imagine we aim to develop a knee brace but we would like to simulate it properly in advance. I see it this way: 1. A new design in ...

Hi all, I am sorry this may be long. I am not sure where I am making the mistake in getting whole body CoM position during a simulation (by loading Inverse Kinematics results). I am trying two methods. My problem is that I cannot get the same results as I do with BodyKinematics analyses. 1. Using "S...

Hi all, I get the same error in Matlab when I use "states = StatesTrajectory.createFromStatesStorage(model, sto)" model = Model(fullfile(model_folder, 'subject01_simbody.osim')); cd('.\IKResults'); model.initSystem() sto = Storage("W1+R+ACC_ik.mot"); sto.setInDegrees(0) states = StatesTrajectory.cre...

Thanks Dimitar! I think I am using the same method you kindly shared. My problem were the following: 1. Why the results are different between this script (that I shared before here) and BodyKinematics analysis in OpenSim GUI? 2. Also, scripting takes a few second to calculate CoM while BodyKinematic...

Hello, Thanks for this post. I am trying to get whole body CoM (center of mass) during a dynamic motion using Maltab Scripts. I have done the following in Matlab and then I did Body Kinematics Analysis to get CoM position. However, the outcomes for CoM are different and Maltab Script takes a long ti...

Hi James, I hope this finds you well. I have noticed that your osimC3D code only gets "markers, and forces". I think in the following line of your code below, we only get markers and forces not all other channels from C3D. tables = C3DFileAdapter().read(path2c3d, ForceLocation) Is there a way we can...
