[Pw_forum] grid of spacing k-vectors

Dear Gabriele,
I have calculated the reciprocal lattice vectors.
I don't get why you said that is the only thing missing.
I have to select k-vectors from the 1st Brillouin zone only, and that's what I can't figure out.
Thank you,

Dear ric,
   I would say that, for a uniformly spaced grid of k-points, specifying the number of k-points is equivalent to specify the grid spacing (along each basis vector of the reciprocal space independently). Since you know the direct lattice vectors, then you can get the length of the reciprocal lattice vectors, which is the only thing missing.

    Dear all,

I'm wondering whether it's possible to generate k-vectors for the
    Brillouin sampling using 
a grid of spacing instead of a number of vectors.
Thank you,
