Dear abinit users,
 
 I want to calculate the bandstructure of N-doped TiO2(rutile phase), and I have build a 2x1x2 supercell,how should I 
 
set the kptbounds so that I can get the whole information of bandstructure ?
 
Can I choose those highest symmertry points some as TiO2 unit cell ?
 
 
PS: from Castep, I found that there is always some universal points for any supercell which  have P1 symmertry.
  
    but  I think those common points may not be able to characterize the bandstructure fully for a given supercell. 
 
Thanks in advances. any advices or hints would be great appriciated !
