This is true.

This is very clever (never thought about that)! 

To make it right, make sure you switch to the co-called "translational
asymmetruc unit" display (click second left image at the bottom
toolbox). Then you save an XSF file. This file will contain a lot of
info. Search for ATOMS section. These are atoms you need!
