</div>This choice of atomic positions seems to be appropriate for "crystal"<br>
coordinates (i.e. coordinates as linear combination of the lattice<br>
vectors), but you are using "cartesian" coordinates (i.e. x,y,z<br>
coordinates using celldm(1) as the unit of measure) which is the default<br>
for pw.x.<br>
<br>
In order to use crystal coordinates you have to specify the keyword<br>
"crystal" after ATOMIC_POSITIONS (on the same line).<br>

What I said for the atoms hold for the k point too, and BTW why are you<br>
specifying them by hand? Normally automatically generated points are<br>
perfectly fine (and way less cumbersome to check).<br>
