[Pw_forum] question about band structure

[Ezad Shojaee]

hi everyone
i want to plot a band structure along a path  in the unit cell of TiO2  & i 
have this error :

from potinit : error #         1
     starting and expected charges differ

what is wrong with my calculation ?
this is my input file for pw.x  :

&control
    calculation='nscf'
    prefix='TiO2',
    pseudo_dir = '/root/pseudo/',
    outdir='/root/tmp/'
/
&system
    ibrav= 7,  celldm(1) =3.785,   celldm(3) =2.5136,
    nat=  6, ntyp= 2,
    ecutwfc =200.0,
    nbnd = 12,
