[Wannier] bands structure of graphene

[Hua-Qing Huang]

Dear all,
  Recently，I want to calculate MLWF of graphene and I have got the sp2-like and 
pz-like MLWF. However, I found that the band strucutre obtained using MLWF 
interpolation doesn't agree well with the band structure obtained form first-
principles calculation (pwscf). What's worse, there is a gap near the fermi 
level, which should be a Dirac cone.
  I have tried different dis_win_max, dis_froz_max, but still can't solve the 
problem. So could you give me some suggestions?
