[ALPS-users] how to define own unit cell

hi , I know the procedure for writing own unit cell i.e., you have to write lattice, latticegraph, unit cell, finite lattice, and graph. But I was trying for Kagome lattice but it wasn't working. So please help me out. I am giving you unit cell for kagome. Please find attached. Description: There are 5 vertices per unit cell. There is one triangle and a line included in that. The coordinates for 5 vertices are (0,0), (a,0) ,(a/2, sqrt(3)*a/2), (a/2, 0) and (a/4, sqrt(3)*a/4). One more thing, how to extract the coordinates of any generated lattice? I am waiting for your reply. Regards, Aniket
