<div>Dear all QE users,</div><div>i am new user;</div><div>i would like 
to calculate InSb band structure by GW PBE. i tried it with GWL and i 
have a result on gamma point only and i would all the band structure.</div><div>So i have a question : GWL treats only gamma point or it could done calculation for various kpoints ? If yes how it does ?</div><div>  <br></div><div>in another part,i am trying SternheimerGW application linked with QE.</div><div>currently,
 i work with QE6.2.0. And when i launch gw.x after scf calculation 
(which runs and converges well)  from tutorial for Si, i have the
