Hello, Sorry for an evidently stupid question. I use g_dipoles to calculate the total dipole moment of the cell evolution. In aver.xvg the following line is present: @ s0 legend "< |M|\S2\N >" @ s1 legend "< |M| >\S2\N" |M| is a modulus of dipole vector. But what are "\S2\N"? Is N a number of particles? And what does S2 mean? Thanks, Vitaly
