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 sam
*Dear users*
*I 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
usin
