this is not "an initial guess". This is "the reference electronic  
configuration"
for the pseudopotential. In principle, you can choose any reference
electronic configuration: if the pseudopotential is transferrable, it  
will
work in other environments as well

please don't write like rappers talk: "want", not "wanna"

you will never get exactly the same numbers, but you should
get very similar numbers, as long as both pseudopotentials
are sufficiently tranferrable
