<p>Dear All,</p>
<p><br>
</p>
<p>I know that this issue have already been discussed, but I could not extract any information that could help me, so I decided to post the issue I had.</p>
<p><br>
</p>
<p>The thing is that if I do a scf calculation with automatic k-points '2 4 5 0 0 0' the calculation runs perfectly fine, and the bandstructure and DOS (nscf with automatic k-points) that I get are totally correct. However when I want to extract the wannier
functions, I know that the atomic positions, k_points and everything must be extactly the same in both the pw-calculation and in the wannier90 inputs. For this, I run a nscf calculation with the kpoint list that is generated from running the perl script kmesh.pl
with kpoint 2 4 5, and I include them all using K_POINTS {crystal} card. When I run the calculation I get an error in routine tetrahedra (I'm using the tetrahedron method) saying '<span>Error cannot remap grid on k-point list</span>'. I've activated the nosym
= .true. tag to see if that could be the problem but the error message keeps appearing. I've also inspected the 18 irreducible k-points from the scf calculation and they look consistent with those generated by the script (not irreducible). I paste the input
file above. Any help and suggestion will be much appreciated.</p>
