<div dir="ltr">Hi everyone!<div><br></div><div>I'm trying to run a full relativistic GW calculation on a CH3NH3PbI3 perovskite. I'm using full relativistic pseudopotentials (such as <a class="" target="_blank" href="http://www.quantum-espresso.org/wp-content/uploads/upf_files/Pb.rel-pbe-dn-rrkjus_psl.0.2.2.UPF" style="font-size:13px;margin:0px;padding:0px;color:rgb(175,16,29);text-decoration:none;font-family:Arial,Helvetica,sans-serif;line-height:18px">Pb.rel-pbe-dn-rrkjus_psl.0.2.2.UPF</a>) but I have some troubles in how to run calculations.</div>
<div><br></div><div>According to the GWL manual I need to run a scf calculation (or nscf one) using a Gamma-only sampling. But, if I want to use a full relativistic pseudopotential I need to use <tt style="color:rgb(0,0,0)">noncolin</tt><span style="color:rgb(0,0,0);font-family:Times;font-size:medium"> and </span><tt style="color:rgb(0,0,0)">lspinorb <font face="arial, helvetica, sans-serif">right. Obviously, as the scf run starts I get the error "</font></tt><font color="#000000" face="arial, helvetica, sans-serif">gamma_only and noncolin not allowed</font><tt style="color:rgb(0,0,0)"><font face="arial, helvetica, sans-serif">".</font></tt></div>
