[Pw_forum] q-point for Negative Bravais Lattice (-12) for lambda.x execution

[Isaiah Moses]

Dear users,
Please I'm doing a PHonon calculation for a monoclinic structure with ibrav
= -12.
I've tried using kpoints.x to generate q-points for lambda.x input file but
there is no negative value among the bravais lattice numbers.

Can some one please advice me on what I can do to obtain q-point with their
weight for a structure with ibrav = -12.

Thanks a lot,
Isaiah
