[QE-users] starting_charge in QE 5.1 version

[Lucas Nicolás Lodeiro Moraga]

Hello! I am facing a problem when i use starting_charge command in 5.1
version.
The problem is:
     Error in routine  read_namelists (19):
      reading namelist system

I am no sure starting_charge is implemented in this old version... I search
for an old pw.x input information, but i cannot found it.

Someone knows if is implemented and how can i use it?

My input is:

                      outdir = './temp/',
                  pseudo_dir = '.',
               etot_conv_thr = 1.0D-6,                  !1.0D-4 default
               forc_conv_thr = 1.0D-4,                  !1.0D-3 default
