Dear Muhammad,

 the error comes from the line
 input_dft = B3LYP ,
 which should be changed to  input_dft = "B3LYP"

 Besides this, the input also shows a number of other issues (no reasons
 for ecutrho > 4* ecutwfc with norm conserving pseudopotentials,
 are you sure you want to use gamma sampling ? etc...)

 In general, I woundn't start directly from a relax calculation, but
 rather from a scf one, where all the relevant parameters could be
 carefully tested (EXX calculations can be very expensive)

take care
Andrea



Dear usersI want to calculate the band gap of my material with B3LYP. However, my calculation fails to run and points out some error in the input file. Can anyone guide me whats wrong with my input file? I have NORCONS pseudopotentials from Q-E
download page and the Q-E version I have been using is 5.0.2.
 he input file is 

&CONTROL
                       title = 'abc' ,
                 calculation = 'relax' ,
