As Tsjerk said, some tools handle PBC well, some don't. If you're having a
specific issue with a specific tool, then you will need to account for
periodicity effects. If not, then there is no need to worry. With
protein-ligand systems and other complexes, -pbc nojump is usually the best
first step. See
