Force plate global ref

Hi,
I am building some models during level and stair walking using the LowerExtremityModel, and just had a quick question regarding the force plates. Do the reference frame of the force plates using ForcePlateType3.any need to be the same as that defined during the capture of the gait data. Currently, the Fx force is positive inferiorly, rather than directed superiorly as recorded with the motion capture software.
Thanks

Hi,

I’m not 100% sure if I do understand correct, but reference frames of the force plates and from motion capture don’t have to be the same. And when you look at the standard GaitLowerExtremity example. The Forces there are inferior as well. I think the best is to compare your data with the standard repository files.
