Illustration of how finite size artifacts lead to concentration mismatches in the bulk: (a) RNA phosphate-counterion radial distribution functions for the Tar-Tar* complex in a 80 Å box of 800 mm NaCl. The anion concentration is ~15% different than the cation concentration at large separations. (b) RNA phosphate-counterion radial distribution functions for the Tar-Tar* complex in a 120 Å box of 800mm NaCl. The anion and cation concentrations agree with each other to within 1% at large radii.
