[Pw_forum] About exchange-correlation functional is PP

[胡树军]

Dear Drs,
I generated the new PPs of atoms: Zn and O, but using the different
exchange-correlation functional, PBE and PW91 respectively, and then used them for
the pw.x calculation. Error appeared at the beginning of the output file. But when
using the some functional, it is successful. Is it necessary to use the same one?
    Best wishes
