Dear Siesta users,
I really really need your help on making the correct supercell.
I am simulating first diameter wire. The supercell I have made is as follows:
LatticeConstant 6.49985 Ang # it is equal to double the cell parameter in
the bulk#
%block latticevectors
5.0000000 0.0000000 0.000000
-2.5000000 4.3301270 0.000000 #hexagonal lattice X 5#
0.000000 0.0000000 0.800570

Although the number of atoms in the supercell is 12 but in the output file I
have 48 atoms.
Please let me know how I can make the correct supercell for this wire and the
ones with higher diameters.
