 command
  command must be used first (unless default setting is used) to tell 
  LAMMPS how many coefficients to expect
a &quot;Nonbond Coeffs&quot; entry only contains one set of coefficients for each
  atom type, after being read-in mixing rules are applied to 
  compute the cross-type coefficients, see the &quot;mixing style&quot; command
  and data_format file for more information
