Hello, When you install the software on Mac you have the option to install for just you or for all users, based on that you may or may not have permissions to the resources folder and/or the folder where the software was installed. The latter would be a problem since the application writes some inte...

Hi Brendan,

The resources/models folder is auto installed the first time you run the installer on your computer, if you want a fresh copy you can follow the steps described below

Hello, A reasonable approach would be to get the number of markers in use from the solver solver.getNumMarkersInUse() Then cycle through this list in turn and print the corresponding names using solver.getMarkerNameForIndex(index) The challenge that the solver is dealing with is that there're multip...

Thanks Mohammadreza,

Indeed the function was introduced post 4.5 but should be available in 4.5.1 which is also available as a conda package.

Hope this helps,

Hello Hanzhe Li, This looks very similar to an issue we fixed lately that was caused by calling the method on markers that are not in the intersection of model markers and those in the trc file. Code innocently assumed names passed in to be valid. Now we throw exceptions but earlier versions would h...

Hello, As described on the page you linked to, using conda packages is the best and most easily supported pathway to getting opensim to work under python. Since you're using version 4.5, you should find the packages here https://anaconda.org/opensim-org/opensim If for some reason you must use the in...

Hi Rahmatullah, Best of luck with your effort to integrate your finite element model with OpenSim. As it stands I'm not aware of a streamlined workflow for this process. Similar to most modeling/simulation environments, OpenSim natively supports importing (one-way) geometry from modeling packages us...

Hi Walter, Thanks for reporting. Can you explain how you're getting the OpenSim python bindings? Basically before version 4.0 we used to build in-house bindings with a fixed version of python. Considering that OpenSim 3.3 was released in 2015 and used the python version available then, it's not surp...

Hi Sunny, The core libraries and scripting interfaces can all be compiled from source on arbitrary new platforms, if you try compiling from source and run into problems please open issues on github and we'll address. As to the GUI/application, it has extra dependencies on more third party tools and ...

Thanks for reporting, For the record, OpenSim version 3.3 used vtk's native libraries to load .vtp files so they were able to parse more vtk based files. As of version 4.0, due to switching to a visualizer that's not based on vtk, we use the Simtk native parsers instead, which are much smaller and w...
