Dear all,

According to Ross's advices, I updated my protocol and I still get
some problems to look at the water...

Here is my new Production :

MD Production
  &cntrl
    igb = 0, ntb = 2, ntpr = 250, ntwx = 500,
    cut = 9.0,
    tempi = 300.0, temp0 = 300.0,
    ntt = 1, tautp = 5.0, taup = 5.0,
    ntp = 1, imin = 0,
    nstlim = 1000000, dt = 0.002,
    ntc = 2, ntf = 2, tol = 0.00000001,
    ntwr = 500, nscm = 2500,
    irest = 1, ntx = 5, iwrap = 1,
    nmropt = 1, ibelly = 0,
  &end
  &ewald
    ew_type = 0, skinnb = 1.0, nbflag = 1, use_pme = 1, vdwmeth = 1,
  &end
  &wt
    type='END',
  &end
  LISTOUT = POUT
  DISANG = R2_restraint

Here is my ptraj input :

trajin R2.mdcrd

center :1-4 mass origin
image origin center familiar

trajout all.traj trajectory

You will find as attachment a screenshot of what I see... Contacts
look now fine but as you can see, I am having some troubles with the
box. Where does it come from? Is it a visualization problem or a
simulation one?
