Hi, I'm getting the same error for the same problematic on musculoskeletal model using the scapulothoracic joint. SimTK Exception thrown at SimbodyMatterSubsystem.cpp1090 Error detected by Simbody method SimbodyMatterSubsystemmultiplyBySystemJacobianTranspose() The supplied spatial forces vector had...

I've found my mistake to run the analyze tool. I finally added external forces .mot and runned inverse dynamics. Plus, I removed this part of the .xml setup file of analyze. <ControllerSet name="Controllers"> <objects> <ControlSetController> <objects/> <groups/> </ControlSetController> </objects> </...

Hello Julian, Thank you for your reply. I saw it in the Tutorial page that they use a CMC result to compute special features. Since I don't have any force plates involved in my trial, I can't perform CMC. Moreover, I think moment arms are more or less a geometrical problem so inverse kinematic data ...

Hi, I'm trying to launch the analyze tool from Matlab on a new model I built. I only want to compute the moment arm from an inverse kinematic file "_ik.mot". So i wrote the following xml file : <?xml version="1.0" encoding="utf-8"?> <OpenSimDocument Version="3000"> <AnalyzeTool name="SA06BM_T0S_R1_m...

Hello, I'm editing an OSIM model trough Matlab 2016b using the Matlab function Xml_writeOSIM.m . The muscles Pathpoints are composed of three types of Points : PathPoint, MovingPathPoint or ConditionalPathPoint. When i'm rewriting a model trough the function the order of the points is changed. And t...

Hello, I'm currently trying to synthesize some MTU (hallux flexor and extensor) in a problem with flexion-extension of the ankle and the knee. Everything works well in open-loop mode and hybrid mode without any muscle synthesized. I'm writing these muscles in the execution configuration files : <syn...
