[Pw_forum] problem in band structure calculation

[Xinxin Yao]

Dear all,
  I meet a problem when doing band structure calculation. The message is:

     nbndx  =   140  nbnd   =   140  natomwfc =   256  npwx   =   40800
     nelec  = 256.00  nkb   =   192  ngl    =    1519
 
     Check: negative/imaginary core charge=   -0.000024    0.000000
 
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

  Any advice will be appreciated!
