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 the order of the pathpoints in OpenSim is also changed. So, the definition of the muscle paths is then wrong.
Is there a way to read right the osim model in OpenSim ? Or is there a way to write better the muscles (in the right order) with the matlab function ?
Best Regards,
Pierre
