Re: Name of muscles

You can right click on the muscle name and chose the show only option. This will show only the muscle that you have selected, then with little knowledge of anatomy you will be able to figure out the name of the muscle.

Re: Extracting the angular velocity

I think the problem is in the setValue, because vector variable is probably in degrees, while Simbody/OpenSim operates in radiance. The execution time is different because the analyze tool is compiled and optimized for speed, whereas the Matlab script file is possibly not or in some case uses JIT co...

Re: Moment arm calculation help needed

One option is to get the column names from the Storage object. Then for each column name find the coordinate in the coordinate set and update its value. However, I think that there is an easier way to update the generalized coordinates from storage directly. Maybe you can search in the opensim-core ...

Re: Newbie problems ...

You can try configuring the project through cmake-gui in order to check whether a correct Java version is selected. I am not sure, but you might need to check the advanced options as well. Each time that you select an option, the new fields will be highlighted with red in the cmake GUI. Make sure th...

Re: Problem Using of OpenSim tools( scaling TRC XML)

You must add the virtual markers of the model according to the market placement during motion capture: https://simtk-confluence.stanford.edu:8443/display/OpenSim/Preparing+Your+Data You can also find a lot of information in the user guide: https://simtk-confluence.stanford.edu:8443/display/OpenSim/U...

Re: Simulink error of opensim-matlab interface

If the Matlab scripts provided by the project works, then the problem is in the configuration of Simulink since they just call the underlying Matlab functions.

Re: Simulink error of opensim-matlab interface

Hi,

This project was created for OpenSim v3.3 and it will not work with v4.0. The source code is made available and with some effort the code can be ported for v4.0.
