Dear AMBER team,
I have two questions and suggestions regarding the usage of polarizable
waters in AMBER.
First, the order of atoms is different for TIP3PBOX and POL3BOX in
solvents.lib. It is O H1 H2 for the former, while H1 O H2 for the
latter. This results in two water types when adding POL3BOX to several
explicit TIP3P waters. Should I change the order of atoms and/or residue
name WAT-->PL3 of the explicit waters to solve it?
Second, I find it misleading having the default water model in
leaprc.ff02 and .ff02EP TP3 instead of POL3 (although I know about
simulations of polarizable solute in TIP3P water). In order to have
POL3P waters with PL3 names, do I add the 3 lines (shown below) after
loading leaprc, before loading pdb and adding POL3PBOX or differently or
twice??
WAT = PL3
set WAT.1 name "PL3"
loadamberparams frcmod.pol3
Looking forward to hearing from you.
Yours sincerely,
Martin Lepsik
