n strategy. The first time we perform 
a CP run after a minimization, it is always better to put velocities equal
to zero, unless we have velocities, from a previous simulation, to
specify in the input file. Restore the proper masses for the ions. In this
way we will sample the microcanonical ensemble. The input section
changes as follow:
<PRE>
           &amp;electrons
              emass = 400.d0,
              emass_cutoff = 2.5d0,
              electron_dynamics = 'verlet',
