MD simulation of POPC (1-palmitoyl-2-oleoyl-phosphatidylcholine) bilayer with OPLS3e force field. 20 w/l. In contrast to previous version, this version contains gromacs format trajectory file popchydr20_10-500ns_step10ps.xtc with corrected time steps. Dataset contains original desmond trajectories (_trj), topologies (-out.cms), input files (.cfg, .msj, .cms), and other files For the ease of the upload, trajectory files (_trj) are divided to 100ns pieces and tarred (named desmond_md_popchydr20_x-xns_.tar.gz) Dataset also contains Gromacs converted files (.xtc, .gro and .top) System: POPC bilayer in water Number of lipids: 200 (100/leaflet) Number of waters: 4000 Simulation time: 500 ns Simulation engine: Desmond 2019-4 Temperature: 300 K
