[QE-users] any tool to get real space force constant from shifted q grid or manually q grid phonon calculations?

the cost of computing the phonon dos with matdyn is zero, compared to the
cost of the phonon calculation itself.

Dear everyone,

As I understand, the q2r.x works only on gamma centered q grids for the
DFPT calculations. However, is there any tool to calculate the real space
force constant for the shift q points calculations and the manually q grid

If it is possible, I want to test the phonon DOS calculation on some
smaller q grids for the sake of saving cost.

Thank for your guidance.
