[gmx-users] Electric potential over the membrane

[Itamar Kass]

    O.K. David, no petty, what should I do to get an electric fields ad 
described in by Robertson & Tieleman at "The molecular basis of voltage 
gating of OmpF porin" (Biochem Cell Biol. 2002;80(5):517-23. ) of about 300mV?
          thanks, Itamar.
