Beta Testers - We need your help testing OpenSim 3.0.1! You'll find it on the OpenSim downloads page, under "OpenSim Release Betas". We've fixed several bugs reported by users and added some new scripting capabilities and examples. https://simtk.org/project/xml/downloads.xml?group_id=91 Some specific things we're looking for help testing: - Scripting in Matlab and the GUI: all of the OpenSim API should now be accessible - The new Matlab optimization example - GUI scripting to plot against a motion and plot moments/moment-arms (see plotMuscleMomentArmAgainstMotion.py) Also, please help us verify the bug fixes: - The checkbox to always load a plugin should work - Iterative scaling in the GUI should behave as expected - SIMM export should be up and running - You should be able to report forces from ligaments in the ForceReporter There are no major changes to the underlying OpenSim API, so your research workflows should otherwise remain unaffected by the upgrade. Please let us know what worked and what didn't by sending me a short email ( jenhicks@stanford.edu). Thanks in advance for your help!
