Hello guys!

Thanks a lot and congratulations to all the members of the developing team for the huge amount of work. I am really excited about exploring the new possibilities Moco provides!

As mentioned during the webinar, I will first try to run the examples in Matlab before going a bit deeper with this new tool. However, I have some trouble making it work, because Matlab does not seem to like having both OpenSim 4.0 and Moco libraries.
Here is what I did :
- run configureOpenSim.m from the "OpenSim 4.0" install folder (Matlab launched as administrator)
- restart Matlab and try "model = org.opensim.modeling.Model()" : everything is fine so far
- run configureMoco.m from the Moco install folder (Matlab launched as administrator)
- restart Matlab and try "model = org.opensim.modeling.Model()".

And there I get a Java exception error, which makes me think I did something wrong :/ any ideas?

Thanks for your help.

Hi, Sam! Thank you for trying Moco so quickly.

You cannot use Moco and a separate installation of OpenSim in Matlab simultaneously. But that's fine, because Moco includes a copy of OpenSim.

Run `configureMoco.m` and edit your Windows PATH to include Moco's bin directory. Make sure Moco's bin directory comes before OpenSim's bin directory.

You do not need to run as adminstrator anymore.

If you still get an error, can you provide the exact error?

We will be posting updated documentation soon. You can look at our temporary updated documentation here: https://opensim-org.github.io/opensim-m ... arted.html.

Hi Chris!
Thanks a lot for your quick answer

I used your procedure and now it works really fine, and I am able to run "exempleSlidingMass.m" without error.

Wonderful!

Have a nice day

Sam

Thanks, I faced the same error, changing the paths order of appearance, in environmental variables worked fine for me too.

Thanks again!!

Thank you, Sam and Mritula. Please let us know if there are other ways we can help
