My question is related to how to use wannier90.</div>

In "wannier90.win" file, I heard that as the value of "num_iter(tag in wannier90.win)" is higher, spread of Wannier function(=WF) is gradually lower in wannier 90.</div>

<b><u>Q1)</u></b> <b><u>If so, is this procedure that minimize the spread of WF meaningful physically??.
</u></b>I think this procedure doesn't represent any material's property, because this procedure can change the picture of WF at any time.</div>

If I use a lot of "num_iter" for any orbital, the spread will be minimized.</div>
