I built a POPE:POPG bilayer in 3:1 ratio. Simplify. Start with pure POPE and pure POPG first. When I am minimizing the bilayer, bonds in head groups are breaking in POPE and POPG lipid molecules. Your topologies are incorrect. Start with a simple test system: a single POPE in vaccuum. w

Dear gmx users, I downloaded POPE.itp and lipid.itp files from Dr.Tieleman website http://moose.bio.ucalgary.ca/index.php?page=Structures_and_Topologies and POPG.itp file from Dr.Mikko Karttunen wesite http://www.apmaths.uwo.ca/~mkarttu/downloads.shtml. I built a POPE:POP
