[Pw_forum] Error in routine bands

[Caroline]

Dear all,

I am doing Pwscf simple tutorials for Silicon. I am collecting band results
for plotting:

bands.in

 &bands
    prefix  = 'silicon'
    outdir= '/tmp/espresso'
    filband = 'bands.dat'

then run bands.x < bands.in

and get the error below

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     Error in routine bands (1):
     gamma_only case not implemented
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Could you please help?
Thanks
