Dear amber friends,

I am trying to simulate a box with two drugs inside, they are the same molecule a figure is attached. I use iwrap in my eq stage , which I understand is the right way to go in multi stage simulations (eq or md production). But I get a warning about only one of the two molecules on the output file, every time a step details are written:

---------------------------------------------------
wrapping first mol.: -42.08192 29.75641 51.53962

 NSTEP = 500 TIME(PS) = 201.000 TEMP(K) = 199.17 PRESS = 0.0
 Etot = -56056.1447 EKtot = 6849.3528 EPtot = -62905.4975
 BOND = 19.7002 ANGLE = 59.8382 DIHED = 136.2303
 1-4 NB = 28.4433 1-4 EEL = -192.3433 VDWAALS = 11463.3184
 EELEC = -74420.6846 EHBOND = 0.0000 RESTRAINT = 0.0000
 Ewald error estimate: 0.2680E-03

What does it mean? Something is wrong?

Here is the input file, as you can see is the first heating stage of 5.

#
&cntrl
timlim=999999., imin=0,
ntx=1, iwrap=1,
ntxo=1, ntpr=500, ntwx=500, ntwv=0, ntwe=0, ioutfm=1,
ntp=0, ntc=2,
ntb=1, ntf=2, cut=9.0,
ntt=3, temp0=150.0, tempi=100.0, ig=-1, gamma_ln=4.0,
nstlim= 100000, dt=0.002,

A grep shows it even clearer:

eq1.out:wrapping first mol.: -63.12288 0.00000 0.00000
eq1.out:wrapping first mol.: -63.12288 0.00000 0.00000
eq2.out:wrapping first mol.: -42.08192 29.75641 51.53962
eq2.out:wrapping first mol.: -42.08192 29.75641 51.53962

Thasnk!!
