Hello, gmx-users.Today I tried to construct a lipid bilayer through a single lipid. The process is like this: 1. editconf -f lipid.pdb -princ -c -box 0.8 0.8 3.0 -o lipid.gro 2. genconf -f lipid.gro -nbox 4 4 1 -o box.gro 3. modified vanderwals radii in the vanradii.dat in the top folder ,changed the C value to 0.3 4. editconf -f box.gro -box 3.2 3.2 4.5 -o box1.gro 5. genbox -cp box1.gro -cs -o mix.gro after these steps ,I got a lipid monolayer and water monolayer got together ,without water in the lipid hydrophobic tails.However when I ran energy minimization steps, it converged to the precision of computer after only 16 steps and still have very high energy. How can I make the starting configuration energy lower? By the way ,I have tried both steep and cg method, neither worked well.Any suggestion will be appreciated, thanks.
