Hi, All:
I have successfully made the cylinder using 72 pieces of the inclined walls, 
the simulation in the QtViewer looks pretty good, however, I want to know the 
position  for each ball at a certain step, I noticed such kind of information 
is stored in the /usr/local/bin/ folder with associated file such as: 
"positionorientation_xxxx", but after I opened this file I do not know how to 
interpret each column, can you provide some explanation of the data file?
I am modifying the SDECSpheresPlane plugin, here is a piece of data obtained 
in the file: positionorientation_3100:
