Hi,

I need to create a graphene surface and I typed the following command in
the console window.

graphene -lx <4> -ly <4> -type <armchair> -nlayers <1> -b <1> -a <1> -d
<1> -i <1>

But I got an error saying, -error graphene: Type must be either 'armchair'
or 'zigzag'

I don't understand what is wrong with the command I typed.

Thanks
Monika
