Four membrane configurations: 1. single = single bilayer (512 MMG molecules and 25600 water molecule) 2. db_large = large double bilayer (1024 MMG molecules and 51200 water molecules)3. id_small = interdigitated double bilayer (256 MMG molecules and 12800 water molecules)4. db_small = small double bilayer (256 MMG molecules and 12800 water molecules) Each membrane configuration has 2 different MMG analogs: 1. MMG1 = MMG-1, 1:1 racemic mixture of stereoisomers with (2R,3S)/(2S,3R) configurations2. MMG6 = MMG-6, 1:1 racemic mixture of stereoisomers with (2R,3R)/(2S,3S) configurations File names: Each trajectory folder contains starting structures, input structure files, trajectory, energy file and system topology file.Additionally, the .mdp files and topologies are located in their own folders. - start.gro = starting structure before energy minimization**- eq.gro = input structure file for production- eq.cpt = equilibration checkpoint file- run.gro = final frame structure file- run.cpt = production checkpoint file- run.tpr = production tpr file - run.xtc = production trajectory file, final 500 ns- run.edr = production energy file, final 500 ns the db_large system is built with equilibrated db_small system, hence the starting structure is before the equilibration. MDP-files: Molecular dynamics parameter files can be found in their own folder (05_mdps/). Files for energy minimization,equilibration and production run are provided. - em1_charmm36.mdp = 1st energy minimization (for all systems)- em_charmm36.mdp = 2nd energy minimization (for all systems)- eq1_noposres_charmm36.mdp = equilibration without position restraints (for single)- eq1_posresin_charmm36.mdp = equilibration with O1 atoms constrained in Z-direction (for db_large, id_small, db_small)- production_charmm36.mdp = production run (for all systems) Topologies and position restraint files: System topologies for each MMG analog can be found in their own folders (06_top/MMG1/, 06_top/MMG6/). Molecular topologies, forcefield parameters and position restraint files can be found from their respective folders (06_top/MMG1/topol/, 06_top/MMG6/topol/).
