Dear all,
Could you tell me how to modify the src file (may be QP_of.F) to add blank lines to the output of o-gw*.qp at each k point.
that is, change from

Code: Select all

Something along these lines

Code: Select all

  ik_ref=0
  !
  do i_qp=1,QP_n_states
     !
     if ( QP_table(i_qp,3)/=ik_ref) then
        ik_ref=QP_table(i_qp,3)
        call msg('o '//what,"","")
     endif
     !                                                                  
     ! Fill the COL type with values                                    
     !===============================                                   
     call OUTPUT_driver(what,TITLES=(/"K-point","Band   "/),I_VALUES=(/QP_table(i_qp,3),QP_table(i_qp,1)/))

Dear Youzhao,

the lines indicated by Davide are found in:
.src/qp/QP_of.F

alternatively, you can post-process the output with an external bash/python/your_favourite script.

Best,

Daniele
