no the input is given in the input format produced by pwgui
it works and the bfgs optimisation runs
but at the end the warning comes to reduce conv-threshold
shall there may be some modification to the file

nat = 8
ntyp = 1
ecutwfc = 40.D0
nosym = .true.
occupations='smearing'
degauss=0.02
smearing='marzari-vanderbilt'
/
&ELECTRONS
conv_thr = 5.D-04,
mixing_beta=0.5,
electron_maxstep = 250
/
&IONS
ion_dynamics='bfgs'
