Dear All ,

I going to calculate phonon density of state  for Ir metal nanocluster. As
a first step  I did scf calculation  with the following input

&control
    calculation='scf'
    restart_mode='from_scratch',
    pseudo_dir='directory where pseudopotentials are stored/',
    outdir='directory where large files are written/'
    prefix='PH',
     pseudo_dir ='/home/farid/QE-5/espresso-5.0/pseudo',
    outdir='/home/farid/Pictures/tmp',
 /
 &system
    ibrav= 0, celldm(1)=7.2560000 nat= 55, ntyp= 1,
    ecutwfc = 25, ecutrho = 250, occupations='smearing',
smearing='marzari-vanderbilt', degauss=0.01,
    nspin=1, starting_magnetization=0, report=1

 /
 &electrons
    conv_thr =  1.0d-8
    mixing_beta = 0.2

After that I did phonon calculation with following input file


phonons of Ir
restart_mode='restart',
 &inputph
  tr2_ph=1.0d-14,
  ldisp=.true.,
  nq1=4, nq2=4, nq3=4
  amass(1)=192.217,
  prefix='PH',
 outdir='/home/farid/Pictures/tmp',
  fildyn='Ir.dyn',
 /

then I get following output
