Dear all,

    I want to use sander to do the energy minimization, with a
distant-dependent dielectric constant of "epsilon = 4r". However, I don't
know how to use a distant-dependent dielectric constant of "epsilon = 4r".
The following is my control data for the min. Is this correct, or I need any
other flags?


&cntrl
  imin=1, ntx = 1, ntxo = 0,
  maxcyc=50000, ncyc = 5000, ntmin = 1, drms = 1.0e-7,
  ntpr = 100,
  ntr = 0, cut = 100, ntb = 0, dielc = 4.0,
&data
  scnb = 2.0, scee = 1.2,
