[Pw_forum] problem in generation of PP with semicore states?

Dear All QE users and developers,

I have problems with generation of PP for Cu(+0.5)  with TM
pseudization scheme , when i  include semicore states.

Without semicore state, i don't have any problem.

But when i include 3s and 3p states in valence,  error comes like-
negative rho, problem in  finding qi coeffs. Rho problem is solved
with PSQ aug functions,
but finding  of qi coeffs is still there.


Please see below  for input file----------------------------

! doubt:
!
!is it ok if I take one 3s and one 4s so that two proj/angular
!momentum. similarly for for 3p and 4p ?

i shall be very thankful to you for your help.
