BOPSgui.m appears, then disappears and errors out

[Nicole Strah]

I am using a Macbook with Catalina (when I updated further, BOPS would not run), OpenSim 4.1, and MATLAB 2021a. I had the same following results or worse with MATLAB 2019b, 2020a, and 2020b.

I downloaded the BOPS-2.0, BOPS_TestData, and Data -- GUI Example folders and put them in my MATLAB folder. (Sidenote: should any of these be nested within another folder?) When I attempt to run BOPSgui.m, the GUI appears for one moment, then disappears and displays the following error messages:

Code: Select all

I have also tried running the program from the main.m file but have had similar issues.

Did I put my folders in the right place? Am I executing this file incorrectly? Do you have recommendations for which versions of OpenSim, MATLAB, and Mac OS I should be using? Do I need to have MOtoNMS downloaded and nested as well?

I found a temporary solution: access the GUI through the BOPSgui.fig file in the MATLAB tree. This will pull up the interactive applet. Unfortunately, the OpenSim model (Model_scaled.osim) is still not able to be selected, so I will make a different forum post addressing this.
