Dear All,
    I am getting following error during Raman spectroscopy calculation in 
QE-6.4.1,
    forrtl: severe (24): end-of-file during read, unit 40, file 
/home2/soumya/qe-6.3/TEST/122/Ba22_prim/raman/RAMAN/./122.a2Fsave

    Error occurs when I use electron_phonon = 'interpolated' but 
completed successfully when electron_phonon = 'simple'. "122.a2Fsave" 
file is also empty. Kindly point out my mistake? Input file is,

Normal modes for Ba22
  &inputph
   tr2_ph=1.0d-14,     !Threshold for self-consistency
   prefix='122',
   verbosity="high"
   outdir='./'
   amass(1)=137.327,   !Atomic mass [amu] of each atomic type
   amass(2)=55.845,
   amass(3)=74.921,
   fildvscf = 'dvscf',
   electron_phonon = 'interpolated'  !method of calculation
   el_ph_sigma = 0.02,               !spacing between double-delta 
smearing values
   el_ph_nsigma = 10                 !number of double-delta smearing 
values
   epsil=.false.,      !must be false for metallic system
   !lraman=.true.      !If .true. calculate non-resonant Raman 
coefficients
   trans=.true.,       !If .true. the phonons are computed.
   asr=.true.          !Apply Acoustic Sum Rule to dynamical matrix
   fildyn='dmat-raman.Ba22' !File where the dynamical matrix is written
  /
  0.0 0.0 0.0          !list of q-points

with many thanks and best regards
