POPC @ 310K, varying amounts of NaCl. Model by Maciejewski and Rog

Input parameter files and parts of the resulting trajectories for a POPC bilayer simulation with varying amounts of NaCl. The systems contain 100, 200, 300 or 400mM NaCl. The force field is an extension to the OPLS-based force field by the same authors [1]. The data for the salt-free system is available at http://dx.doi.org/10.5281/zenodo.13498
