Hello :
   I found a strange information from AMBER ouput:
  NSTEP =    10000   TIME(PS) =     320.000  TEMP(K) =   298.10  PRESS 
=  -418.2
here is my .in file:
equilibration
&cntrl
   imin=0, irest=1, ntx=5,
   nstlim=250000, dt=0.002,
   ntc=2, ntf=2,
   cut=10.0, ntb=2, ntp=1, taup=2.0,
   ntpr=500, ntwx=500, ntwr=5000,
   ntt=3, gamma_ln=2.0,
   temp0=300.0,
   ntr=1, restraintmask=':288|:1-287.CA,C,N',
   restraint_wt=1.0
/
I use timestep 0.002, if it is at 10000, the time should be 20 PS.... 
Why doesn't the output file claimed to be 320 PS?
thank you very much.
