Hello,
I have a question about example 10, which does calculations on PbTiO_3. The 
number of valence electrons specified is 25,  nbnd=25, corresponding to a Ti 
cation (4s2 3d1) and the Ti pseudopotential , Ti.vdb.UPF also states that it is 
generated for the cation, 
Wavefunctions         nl  l   occ
                            3S  0  2.00
                            3P  1  6.00
                            4S  0  2.00
                            3D  2  1.00
Giving 11 valence electrons corresponding to 4s2 3d1. 
THough in the same file it states 
   12.00000000000      Z valence
Is the calculation really being carried out for  PbTiO_3 with a titanium cation 
and the rest neutral atoms? IF so why? Or is there something I am 
misunderstanding about how the pseudopotential and run file are made?
Thank you,
