title: POPC @ 310K, varying water-to-lipid ratio. Model by Maciejewski and Rog
author: Javanainen, Matti
description: Input parameter files and parts of the resulting trajectories for a POPC bilayer simulation with varying water-to-lipid ratios. The used ratios are 50, 25, 20, 15, 10, and 5. The force field is an extension to the OPLS-based force field by the same authors [1]. The same POPC force field has also been employed in [2]. –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– Files: XX.tpr – XX waters per lipid; run input file for Gromacs versions 4.5.5 and above.  XXWperL_YYns.xtc – The last YY ns of a 100 or 90 ns long simulation (50 ns discarded from the beginning).
