[Pw_forum] inconsistent DFT read

Dear Pan,

I think you simply didn't take care of your pseudopotentials.
NiUS.RRKJ3.UPF and As.gon.UPF corresponds to a PZ (LDA) functional but
Ba.pw91-nsp-van.UPF sets PW91 (GGA) as a functional. Also take care
that you're mixing ultrasoft and norm-conserving pseudopotentials, so
you might need a higher ecutwc and ecutrho.

Yours,
Marton
