Probe Reporter on Moco Solution

[Luke Jessup]

Hi all,

Anyone have experience running the probe reporter (analyze tool) on their solution from moco?
I've attempted with the controls and states (example files attached) generated by moco, which does output metabolics, but the outputted motion shows the model contorting. Is there anything that I might be missing when it comes to prepping the controls and states from moco for the probe reporter?
(I am using the Umberger 2010 Probe)

Thank you,
Luke

Hi Luke,

The ProbeReporter shouldn't change the kinematics of your solution. When you visualize the states that you input to the reporter, do the kinematics look normal? Are you using the AnalyzeTool via the GUI? How are you setting it up?

Thanks for your reply, Nick!

I had another look and realised that I misplaced a few values when I was compiling the states file - all is working now.
One other query that I have, is that when I load the probed model with DGF muscles into the opensim GUI I receive warning messages about muscles/actuators not being found and being ignored. Might this just be because opensim doesn't recognise DGF muscles, as the output from the probe reporter still gives me values alike https://simtk-confluence.stanford.edu:8 ... bolic+Cost, and when I try with Millard muscles these warning messages don't appear... or is this likely because of something else?

Cheers

Hi Luke,

If you're using one of the more recent versions of OpenSim, which include Moco, the GUI should recognize the DGF muscles and not throw those errors. Glad you're getting realistic values either way though.

That was it. Thanks, Nick.
