[gmx-users] duplicate the lipid bilayer

[Yuhua Song]

Hi, Rainer:

Thanks for your kind response. After I get 256 DPPC bilayer, if I only want
to simulate a system of 200DPPC, could I also use editconf to modify the
system to get a 200DPPC bilayer? If it can, how I can realize it?

Thank you very much,

Yuhua
