description:
Simulations of a POPC bilayer with varying amounts (0, 10, 20, and 30 mol-%) of cholesterol and 130 mM of NaCl performed at 310 K. The POPC bilayer consists of 200 lipids (100 per leaflet) and on top of that there is 0 (0%), 22 (10%), 50 (20%), or 86 (30%) of cholesterol. The Charmm36 model [1,2] is employed for lipids, the Charmm compatible variant of the tip3p model for water, and the standard Charmm ion parameters for NaCl [3]. The Charmm36 force field parameters were obtained Charmm-GUI [4]. IMPORTANT: The simulations are performed with version 1.7 obtained from Charmm-GUI, and this version is known to have an issue with the multiplicity of dihedrals in Gromacs output files, see http://www.charmm-gui.org/?doc=log .  –––––––––––––––––––––––––––––––––––––––––––––––––––––– The files are in GROMACS format and named based on the amount of cholesterol present (in %) in the corresponding simulation. Trajectories (.xtc) are 200 ns long with data saved every 100 ps. Additionally, the final structure (.gro), topology (.top), index file (.ndx), energy output file (.edr), and binary run input files (for Gromacs 5.0->) (.tpr) are provided for each system. The common simulation parameter file (.mdp) is also provided. –––––––––––––––––––––––––––––––––––––––––––––––––––––– [1] Update of the CHARMM All-Atom Additive Force Field for Lipids: Validation on Six Lipid Types.
