i'm new to OpenSim API. I'm trying to change one of the Property ('POINT') inside the PointKinematic within an Analyze.XML file. In OpenSim 3.0, this's can be done using 'PropertyHelper', but in OpenSim 4.1 this function was deprecated. I wonder if anyone know how I can change the coordinate of the Point or any Property inside an XML file via matlab API.
Code: Select all
AnalysisSet = analyzeTool.getAnalysisSet()
PK_Analysis = AnalysisSet.get(1);
(-0.172322 0.0400191 0.00588038) = PK_Analysis.getPropertyByName('point')
????

In both Matlab and GUI scripting, OpenSimContext, PropertyHelper, and ArrayDouble are deprecated. These helper functions are no longer necessary since Simbody classes such as State and Vec3 have been exposed. For more information, see Common Scripting Commands.
