[Pw_forum] force and stress in the Berry phase method

[hanghui chen]

Dear PWSCF users,
    In addition to my previous email, I would like to know: if I use
ultrasoft psedopotential, are the forces and stress correctly calculated in
the Berry phase method in the latest version 4.0.4?
    Thank you very much.
