Shown in parentheses are data for simulations with Charmm parameters for ions.

Total time of a simulation run.

Time before pore formation.

§

Transmembrane potential induced by an ionic charge imbalance before pore formation.

Corresponds to the leakage of the first ion, the type of the first leaked ions being indicated as a superscript.

Corresponding radius of the inner part of a water pore assuming an ideal cylindrical shape.
