[Pw_forum] the scf.in file for Phonon dispersion calculation

[yhho]

Dear all,
I'm doing phonon dispersion now.
And I have an big question about what do I put on the last part of scf.in

 &control
    calculation ='scf'
    restart_mode ='from_scratch'
    pseudo_dir ='/lustre/lwork/dyyang/bin/espresso-4.0.3/pseudo/'
    outdir ='./'
    prefix ='AuC'
 /
 &system
    ibrav =4
    celldm(1)= 4.6514
    celldm(3)= 2.3000
    nat =  2
    ntyp =  1
    ecutwfc = 24.0
    ecutrho =  240.0
    occupations ='smearing'
    degauss= 0.02
 /
 &electrons
    diagonalization= 'david'
    conv_thr =   1.0d-12
    mixing_beta =  0.7

   0.3750000  0.3750000  0.6250000   3.00

Now I'm using the K_PONITS which examples applyed but the result is still bad.
I think it's wrong to use example k-ponits.
but I still don't know what should I put on it.
Please give me some suggestions. Thank you very much.
