These are warnings, and you should not adjust too much particularly when you have a complex structure with (perhaps) inaccurate atomic positions. I suggest just using -7, your use of -10 (?) was not needed.</span></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:#000000"><span style="color:rgb(34,34,34)"><br></span></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:#000000"><span style="color:rgb(34,34,34)">3) Beware that Vasp can reduce symmetry inappropriately.

<br>
If it is later, make sure :NEC01 is ok in the scf fle.<br>
<br>
Check case.scf1 to see where the actual E-parameters for atom 5 l=2 are.<br>
If the E-parameters for APW and for the LO are too close ---> ghostbands<br>
<br>
<br>
Are you sure you need the Sn-s semicore states ??<br>
