Dear QE Users,

Following example 19 in the PHONON package, when I run postahc.x on the following input with QE-7.3.1:

&input
  prefix = 'PbTe'
  outdir = './'

  ahc_dir = 'ahc_dir_coarse/'
  flvec = 'PbTe.modes_coarse'
  ahc_nbnd = 10
  amass_amu(1) = 207.2
  amass_amu(2) = 127.6
  ahc_nbndskip = 0

  eta_eV = 0.1
  efermi_eV = 6.565
  temp_kelvin = 700.0
/

I get the following error:

     from postahc : error #      5010
     error reading input namelist

This error is usually caused by incorrect spelling or syntax. The input is taken from example 19. Before trying to debug the postahc.x code, has anyone seen this error in postahc.x or knows how to avoid it?

Thanks,
Vahid
