I am having a little bit of a problem getting the coordinates of the atoms in the "surface cell" right. I thought that this should be a standard problem, but I can't find anything about a suitable algorithm for doing this neither on the Web nor in standard crystallography text books. If anybody has any pointers either to code or text books on this subject I would appreciate it. Best Regards, Jrg-Rdiger Hill
