EDEMpy particle properties

Hi,

I am working with EDEMpy on ellipsoids and polyhedra. I am trying to retrieve particle properties for these shapes, but I cannot find any documentation on EDEMpy.

1. How can I obtain properties of the particles, such as nodes or orientation?
2. Regarding orientation, there is a function that returns the quaternion of the body, but it does not specify the reference point. For example, when dealing with a sphero-cylinder, what is the reference point of the quaternion? Is it a vector on the minor or major axis?

Cheers, 

MC
