[Pw_forum] regarding 'bands' calculation

[kulwinder kaur]

hello
i am doing Mg2Ge calculation. 'scf' calculation done well but when i run
'bands' calculation. this error occur
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     Error in routine setup (3):
STOP 2
     problem reading ef from file temp/mg2sGe.save
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

     stopping ...
 i am also pasting both input files

 (scf calculation)

&control
    calculation = 'scf'
    restart_mode='from_scratch',
    prefix='mg2Ge',
    pseudo_dir = '.'
    outdir='temp'
     verbosity= 'high'
    wf_collect=.true.

&system
    ibrav=  2, celldm(1) =12.056451807, nat= 3, ntyp= 2,
