    <p>Using the cif you sent, I get the following:<br>

    <p>Now, if I open Li3Ni2SbO6.cif in VESTA [1], click Edit -> Edit

      the wrong setting for WIEN2k.  I select the <font color="#0000ff">B

      OK, click File -> Export Data, and Save the new cif file.<br>
    </p>
    <p>Then, when I rerun with the new cif file, I get the following:</p>
