Second: Am I simulating fixed connections? No I once wrote in a mail in may I think: This may be a really simple question, I know, but still... How can I set up a fixed connection between two atoms of a molecule? When I choose the 5th bondtype in my topology-file I get the following

Hi, I just have a couple of things i want to clarify about the constrain distances i used. The distance I used to pull the ligand and receptor apart was a non-bonded distance between the amide nitrogen of the ligand and the oxygen carbonyl of the receptor (on both ends). looking at the

[gmx-users] construct lipid bilayer from a single lipid

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
