Data to accompany "Influenza hemagglutinin drives viral entry via two sequential intramembrane mechanisms" by Anna Pabis, Robert Rawle, and Peter Kasson. Publication at doi:10.1073/pnas.1914188117 This package contains: Topology, itp files and starting conformations used in the simulations. The files are organized in folders named "Model_Start-state_Parameters" where model, start state and parameters correspond to a given simulation (see Table S1 for the list of all simulations) Abbreviations used in folder naming: CG = coarse-grained Docked = Docked proteoliposome Stalk = Initial stalk Stalk_Exp = Initial Stalk, larger bilayer Post_Stalk = after stalk formation with CG NH3-Gly Pre_Pore = 10ns prior to pore opening in CG NH3-Gly simulations
