Dear users and developers of Quantum Espresso,<br><br>I am using espresso-4.3.2. I was looking at the code to generate the Monkhorst-Pack grid of q-points for the phonon calculation (in the PH/q_points.f90). It calls a subroutine kpoint_grid to calculate the grid of q-points for the specified values of nq1, nq2 and nq3 in the *.<a href="http://ph.in">ph.in</a> file.<br>
I then checked the kpoint_grid subroutine (PW/kpoint_grid.f90). This is the same subroutine that calculates the k-point grid for the SCF calculation.<br><br>I ran the scf calculation to obtain all the k-points generated in the first BZ, I found to my surprise, that the k-points generated by pw.x and ph.x are not the same.<br>
<br>I would like to know the reason behind this or what sort of an operation has been done to get this difference.<br><br>Any help in this regard, would be appreciated.<br><br>Many thanks in advance<br><br>Cheers,<br><br>
