Hello developers,
Did the convention for the direction of X, Y and Z with respect to Muscle-Induced Accelerations of the centre of mass (as calculated using the Perturb application) change between OpenSim versions 1.5.5 and 1.8.1 ?
I have just processed the same CMC output through the Perturb tools in both those versions and it appears that the vertical direction that was Y in version 1.5.5 is now Z in version 1.8.1 ...
Was this an intentional change or am I missing something?
Cheers,
Tom
