How can we plot bandstructure with M,K points in ATK-VNL

I try this method but iam able to find bandstructure with M.K points for only single crystal of graphene. but when iam trying with sheet iam not able to get bandstructure with M,K points. So, Please help me .

It is not required...., specially when the Structure is in the form of a sheet or a Ribbon..... Route through G,Z....that will suffice the case....

Precisely. The symmetry points M,K etc are not related to the material or atoms (graphene) but the shape of the unitcell. So if the cell is not hexagonal, the symmetries are different and M,K don't make sense.
