Dear Wannier developers,</div>

I have tried to run the <i>Wannier interpolated electronic band structure</i> of Cu in tutorial6 with the input files given in this link:<a href="https://github.com/wannier-developers/wannier90/tree/develop/tutorials/tutorial06" id="LPlnk">https://github.com/wannier-developers/wannier90/tree/develop/tutorials/tutorial06</a>.
I realized that:</div>
<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
1) the mass of Cu in scf (63.546) and nscf (55.85) file is different and the number of kpoints in scf (16x16x6) and nscf (64) are also different.</div>
<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
2) I used ultrasoft pseudo cu_pbe_v1.2.uspp.F.UPF, this gave rise to completely different band structures as Cu.pz-n-van_ak.UPF pseudo (even the copper_band.gnu file did not present the lowest value in yrange, just *******:)</div>

Would you please so kind give me some explanation on these issues?</div>

Thank you very much in advance</div>
