[Pw_forum] Question on supercell calculation of MgB2

[张 洪彬]

Dear all:
  Now I am doing a 2*2 supercell calculation of MgB2, however, there is a 
warning like this:

Warning: ef = 1.818386 is above the highest band at k-point 490
         e  = 1.780277

and there are also warning on other k-points, but not all. Please tell me 
why. Thank you.

Regards.
