Definition of surfdos_l and surfdos_r ?

          Yes, exactly. Some times the atoms on these two dual surface are different. 

You have to keep in mind that we consider the unit cell as one atom. It means WannierTools don't cut the atoms on the surface exactly the same as experiment. So you can find the atoms on the outer surface if you put the unit cell on the lattice you cut.

Dear Mr. Wu
Hello. I am also confused by the definition of left and right surface DOS. Where should I refer to?
I used to refer to POSCAR_slab for configuration of the edges, but I found when I try to cut a armchair edge of honeycomb lattice, though the two edges are identical, as given by POSCAR_slab, the surface_l and surface_r are still quite different.
