[gmx-users] Parameters for PB calculation with Delphi from Gromacs data

[Marc Baaden]

Hi,

I am currently carrying out some Poisson-Boltzmann calculations with
Delphi, on the basis of MD snapshots obtained with Gromacs. I wonder
what parameter set (charges & radii) would be appropriate for Delphi.
Should one "simply" take the precise charges as used in the MD simulation,
and eventually the VDW-parameter derived atomic radii, or is there some
other magic involved to obtain reasonable results ?

What are people's experience, and would users be willing to share their
favorite parameter set ?

In particular I wonder whether one would need to have different specific
Delphi parameters depening on the forcefield used (ffgmx vs ffG43xx vs
oplsaa) ?

Or maybe it is more appropriate to use MEAD, as some Gromacs tools allow
to write corresponding input structures ?

Any clarification or (Gromacs related/specific) litterature reference is
welcome.

Thanks in advance,
  Marc
