Dear PWSCF users,<br> <div id=":8h" class="ii gt"> I have done
geometry optimization for thin films of different systems. Now I want
to calculate the band structure of the compound. Can anybody please
give me a direction for the same. I am pasting a sample input file for
the geometry optimization for silver.<br>
