After running saveAmberParams in the tleap, Ireceived the warningWarning: The unperturbed charge of the unit (-4.000000) is not zero.I have seen Amber tutorials using explicit water models which resolved thiswarning by adding Na+ and Cl- ions (i.e. addIons mol Na+ 0 and addIons molCl- 0) until the charge was neutralized. However, if I am using an implicitsolvent model (i.e. igb=8), do I still need to neutralize the charge byadding ions? On a more general note, how would I go about adding ions intleap (even if it was not for the sake neutralizing the molecule) forimplicit solvent simulations?Thank you,Conrad Li_______________________________________________AMBER mailing listAMBER.ambermd.orghttp://lists.ambermd.org/mailman/listinfo/amber
