I think the input to dos.x (I call it <a href="http://dos.in" target="_blank">dos.in</a>) looks like this:

<div>You run dos.x after the nscf run. I think the <a href="http://nscf.in" target="_blank">nscf.in</a> should contain the relaxed structure.</div>

<div>For the definition of Emin, Emax and DeltaE, see the online dos.x manual.</div>

</div>
<div>I am trying to extract the DOS profiles for some graphene systems using Supercomputing facility.<br>
</div>
<div><br>
</div>
<div>First, I performed VC-relax and then NSCF (I have not manually updated the relaxed coordinates in the nscf input file, since nscf automatically reads them from previous scf run). Then I tried to execute dos.x, however I am getting segmentation
fault error as shown below.</div>
