Change Pelvis' Axes Position

Post by Ezequiel Martín Sosa » Tue Oct 20, 2020 8:23 am

Dear OpenSim community,

I am studying a new markers protocol and I need to change the position of the pelvis' axes position (local coordinate system position). The position of the axes in the standard model gait2392 is located on middle point between the RASI and LASI markers. My designed position is different and I can't change the relative position of the markers located on the pelvis. My question is: Is there any way to change the axes position?

Kind regards.

Ezequiel

Hi,

You can check the orientation in child property of the joint associated with the pelvis body.

Please have a look at GCMAS tutorial 2014:

https://simtk-confluence.stanford.edu/d ... orial+2015

There, the model has different access so that it is in line with the CGM (conventional gait model) protocol.
