[Wien] About (7,3) chiral nanowire

[A SEN]

Dear Wien users,
                If I want to generate the coordinates of a triangular
lattice for a (7,3) chiral Au nanowire to find the energy
stability using WIEN2K, how should I proceed? I would
greatly appreciate if you could please help me out in
letting me know of the 1D version of the WIEN2K code.
Best regards,
Sen
