As I am new to QE, what changes should I make in the xspectra input file? Should the calculation be 'xanes_dipole' itself? Does the xspectra module generate the 'O.pbe-nl-kjpaw_psl.1.0.0.core1s.wfc' file, or do I have to create it by running some other module and then give it as an input to xpectra?</div><div dir="ltr" style="font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;"><br clear="none"></div><div dir="ltr" style="font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;">Please help me in this regard.</div><div dir="ltr" style="font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;"><br clear="none"></div><div dir="ltr" style="font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;">Regards</div><div dir="ltr" style="font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;">Akhil</div><div dir="ltr" style="font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;">HBNI, INDIA</div></div><br></div></div></body></html>
