[QE-users] Error in DOS calculation

[Smarak Rath mm18d201]

Dear Friends
I successfully completed scf and nscf calculations for my system. But when
I do the DOS calculation using dos.x, I get the following error:

     Error in routine  fft_type_set (6):
  there are processes with no planes. Use pencil decomposition (-pd .true.)
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

     stopping ...

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     Error in routine  fft_type_set (6):

This is my nscf file:

This is my dos.in file:

&DOS
  prefix = 'het2'
  outdir = './out/'
  Emin = -70.0
  Emax = 30.0
  DeltaE = 0.01
  fildos = 'het2.dos'
/


Can anyone tell me what might have gone wrong?
