[Pw_forum] mixing pseudopotentials using virtual.x

[da wang]

Dear all:

I have met a problem when I used virtual.x to mix pseudopotentials of O
and F (http://www.quantum-espresso.org/pseudo/1.3/UPF/O.pbe-van_ak.UPF,
http://www.quantum-espresso.org/pseudo/1.3/UPF/F.pbe-n-van.UPF)

it says:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     from Virtual : error #         1
     different nqf are not implemented (yet)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

I want to know how to do it correctly?

Thanks in advance.
