Hi Nick Thank you for your response. I checked the topology and looks fine. This time I tried running addbiomechanics with the same model but removed the joints that are welded (radioulnar and wrist) and i get the following error: ['/app/../engine/engine.py', '/tmp/tmp5c4peohz/', 'Pilot_test_1', 'ht...

Hi, I recently used addbiomechanics to generate IK for my walking data using a custom model (modified Rajagopal model) and i encountered the following error. It appears that the model I used may not be compatible with the algorithm. Can you please provide guidance on how to resolve this issue? Thank...

Hi all, Why is there an offset between experimental grf and marker data when we preview them in OpenSim? I know that i can adjust the offset to align the grf with the markers but i would like to know why they do not overlay automatically in OpenSim and is there a way to change the display? Thanks, S...

Thank you Prof. Uchida, will try the mentioned methods.

Thanks

Hi

Is there a way to generate a scaled model in Matlab directly instead of running an XML file in OpenSim GUI using the scale tool? I could create an XML (scale setup) file in Matlab with a piece of code but could not generate a scaled model with that XML file.

Thanks,
Sheeba

Hi Ayman

Problem solved. It was the issue with display adapters, which i had to install for the visualizer to work. Thank you.

Hi, I downloaded OpenSim 4.4 and integrated it with Matlab. But the visualizer does not work when i say study.visualize(fullStride); following is the error i get Java exception occurred: java.lang.RuntimeException: SimTK Exception thrown at VisualizerProtocol.cpp:728: Error detected by Simbody metho...

Hi Ross Thank you very much for your suggestion. I have enabled modelProcessor.append(ModOpTendonComplianceDynamicsModeDGF('implicit')); and ran the tracking simulation and used the solution to run predictive simulation. Initially with a MetabolicCostWeight = 1.0, the solution did not converge and i...

Hi, I was trying to generate a tracking solution without a guess file (by uncommenting the code to set the normalized tendon forces to reasonable values in the guess) in order to use that solution to run the predictive simulation. The tracking solution looks fine but the file does not have 'normaliz...

Hi Ross

Thank you very much for your suggestion. I will try it and update it here.
