<pre class="net-thunderbird-android__plain-text-message-pre"><div dir="auto">Dear Wannier Users,<br><br>When trying to wannierize the band energies generated by external codes such as HSE or GW, one can modify the .eig file but the .mmn and .amn are still based on the nscf calculations. I do not believe that the Wannier code accepts an external file of energies instead of the nscf calculation. Is there a tool that allows the generation of the .mmn and .amn files consistent with an external energy file (and not the one generated by the nscf)?<br><br>Thanks,<br>Vahid<br><br>Vahid Askarpour<br>Department of Physics and Atmospheric Science<br>Dalhousie University<br>Halifax, NS, CANADA<hr>Wannier mailing list<br>Wannier@lists.quantum-espresso.org<br><a href="https://lists.quantum-espresso.org/mailman/listinfo/wannier">https://lists.quantum-espresso.org/mailman/listinfo/wannier</a><br></div></pre></blockquote></div></body></html>
