[gmx-users] Adsorption layer of water molecules

2013-02-06 Thread Yara Alves
I'm working with a protein in water and I used periodic boundary conditions in three dimension. At first the initial system was minimized, then I followed Justin's protocol. The system was equilibrated in a first stage nvt for 1 ns and in a second stage npt for 1 ns (with restraints). Then the
