If you have performed a correct SCF using your decreased lattice parameters, you can look at the case.qtl after x lapw2 -qtl (taking up and dn flags ...) and case.dos1 after running x tetra to chechk whether they contain non zero results or no. In the former case the DOS's can be appeared. In the later case you would check the error files to find the source of the problem. And if there is no error, I am not sure whether it is possible to be all your valence states in the interstitial region?<br><br><b><i>jingyun_1984@sohu.com</i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> <meta http-equiv="Content-Type" content="text/html; charset=GB2312"> <!--SOHUMAIL_HTML_HEAD_END-->Dear Wien users and developers!<div>I want to calculate and plot the</div><div>DOS at ambient and high pressure of my case，which is fcc structure.</div><div></div><div>I am running the scf cycle with runsp_lapw (no
