[Pw_forum] Pseudopotential dependent projection when using DFT+U

Dear Zhongnan,

  I'm sorry, I confused two answers on two different email forum - on two
different codes.

  Answering _your_ question, yes, the basis set is determined by the pseudo
potential, with the atomic (pseudo) wave functions given in the same file
as the pseudo potential itself.

    Sorry again for the confusion, :(
