Hi all,

I'm not sure I understand how to set the relative dielectric constant, when dealing w/ charged bead type interactions in Martini. Should I be setting it's value to 15 regardless of the dielectric constant/level of charge screening going on in the corresponding system? If so, is there some justification for this choice - or any differences in how the dielectric constant is treated between Martini V. 2.2 & 3.0?

The Martini FF has been parametrized towards dielectric screening constant of 15, part of the electrostatic interactions have been included in the LJ parameters, therefore changing the screening constant would mean that you would also have to parametrize the LJ interactions. In short we would not advice fiddling with the screening.
