<div style="margin:0px;font-size:12pt">I would like to calculate
the wave function of the k point in the full BZ from the wave
function in irreducible BZ. So, some symmetry operations are
needed. I'm wondering if there are already some subroutines
doing such jobs. Or any hint on how to do that?</div>

<p>Hello, it is already done it at least two places: the exact
exchange code and the pw2wannier90 code when you are using
symmetry-adapted functions. The little post-processing code
open_grid.x will do this exact same operation, reusing the exx
code. It is straightforward in serial, but a pain to do in
parallel. <br>
</p>
<p>kind regards<br>
