Dear Gromacs Users,

I am still struggling with PS_PC system for quiet a long time. I want to distribute some DPPS lipids (Negative changed) in one leaflet of DSPC (Neutral) membrane, however, the PS lipids go to both leaflets after EM simulation. How to restrict PS just in one side?

Mention: If in 128 lipids membrane and the PS lipids are less than 35, PS lipids can stay in one leaflet of a membrane stably.

So Can you help me for this?

Thanks Millions,
