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">https://github.com/wannier-developers/wannier90/tree/develop/tutorials/tutorial06</a>.
I realized that:</div>

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 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>
