Dear All,

I am trying to optimize NH3 molecul.
The error was:
from readpp : error # 2
inconsistene DFT read

My input file was:
&control

restart_mode='from_scratch',
prefix='nh3',
disk_io='low',
wf_collect=.TRUE.,
pseudo_dir='',
outdir=''
/
&system
ibrav = 0,
celldm(1)= 1.0
nat = 4,
ntyp = 2,
ecutwfc = 16.0,
nbnd = 128,
ecutrho=200.0,

mixing_beta = 0.7,
conv_thr = 1.0d-6

I did not see this error before.
I great appreciate all your instructions.
