Hi, > Yes. You can use GROMACS to simulate traffic if you want to. :-)

Well, probably this is due to the fact that you only use a 1.0 nm distance from the solute to the wall, which makes the box dimension 2.0+peptide dimension, together being less than twice the cutoff radius used (2*1.4=2.8) for at least one direction. Increasing the box dimensions will solve the problem. If you're going to work with more small peptides, it's good to just set the box at 3 nm or so (editconf -f protein.gro -o out.gro -bt dodecahedron -box 3.0). Cheers, Tsjerk -- Tsjerk A.
