<div>Dear Fhokrul,</div>
<div><br>
</div>
<div>Your procedure looks fine.<br>
</div>
<div><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>Here I have some questions:</div>
<div><br>
</div>
<div>(1) Is there no [-c] in your lapwso ..?</div>
<div><br>
</div>
<div>(2) Are there both of [in1] and [in1c] in your directory?</div>
<div>If yes, could you delete the [in1], before the [lapw1~lapwso] ?</div>
<div><br>
</div>
<div>(3) Could you try to do [x wannier90 -pp], just before [x w2w] ?</div>
<div>And could you try to use [x w2w -up -c -so], instead of [x w2w -up -so] ?</div>
<div>(<<< I think they are the same,,, but just for checking ...)</div>

<div dir="ltr">Dear Fhokrul,<br>
<br>
<br>
I also usually do some calculations with [run_lapw -so].<br>
(i.e., not runsp_lapw)<br>
<br>
So I may be I can share my experiences.<br>
<br>
<br>
In my case, the procedure is following:<br>
<br>
<br>
########################################<br>
### PART 1. WIEN2K ###<br>
########################################<br>
<br>
\cp case.vns case.vnsup<br>
\cp case.vns case.vnsdn<br>
\cp case.vsp case.vspup<br>
\cp case.vsp case.vspdn<br>
<br>
x kgen -fbz (no shift)<br>
<br>
x lapw1 -up (and with the additional options from the dayfile)<br>
x lapw1 -dn<br>
x lapwso -up<br>
<br>
<br>
########################################<br>
### PART 2. WIEN2WANNIER & WANNIER90 ###<br>
########################################<br>
<br>
write_inwf -up<br>
write_inwf -dn<br>
write_win -up<br>
<br>
write case.fermiup and case.fermidn<br>
<br>
x wannier90 -pp<br>
x w2w -so -up<br>
x w2w -so -dn<br>
wannier90 -so<br>
<br>
<br>
The above procedure works fine for me.<br>
Is there any difference from yours?<br>
<br>
<br>
Have a nice day.!<br>
