Dear Amber users!
>From the Amber tutorials I've learn that initial heating should be always
done in NVT and production run in any desired ensemble. Supposing I'm
using NPT for production run performing 100ps NVT pre-equilibration of my
water-soluble system with applied position restrains on all atoms of my
protein. Should I do a short NPT equilibration as well (taking all outputs
from the previous NVT) with the such position restrains applied to the
protein (as I've found in the Gromacs tutorials). What fluctuation to the
system might be introduced by its initial coupling with the Monte Carlo
barostat (for instance seriously deforming protein conformations during
beginning of the NPT phase if pos.res on protein atoms have not been
applied) ?
TFH,
James
