Subject: AMBER: TIP5P water simulation with AMBER7

Dear Users,
          I am trying to do a TIP5P water (216 molecule) simulation in NPT
ensamble at P=1 and at different temperatures starting from 300K to 210K. The
input file i am using for that is of the following structure....
   irest = 1, ntx = 7,
   ntb = 2, ntp = 1, taup=0.5,
   cut = 8.0,
   ntf=2, ntc=2, tol=0.000001,
   nstlim=200000, ntpr=100,
   NTWX=10,NSCM = 1000,NTWR=500,
   ntt=1, temp0=300., tautp=0.5,
  But, I am not getting the density profile of the TIP5P water correctly.
Can anybody please suggest me some useful modification of the above input
file to reproduce the density correctly. Any suggestions will be highly

Thanking you.
