Can the center command recenter my inpcrd file ? I
know
it can reimaging the trajectory back into the primary
box. but it seems no effect to my mdcrd files.

In the step 1 MD ,I raised the temperature from 0 K to
356.65 K
tempi = 0.0,
temp0 = 356.65,.
In the step 2 MD , I reduced the temperature from
356.65 K to 300K .
tempi = 356.65, temp0 = 300.0,
I am not sure it is right .
thanks very much !
