| VERSION 4.6.1 |
A small program to reduce a two-phase density distribution along an axis, computed over a MD trajectory to 2D surfaces fluctuating in time, by a fit to a functional profile for interfacial densities A time-averaged spatial representation of the interfaces can be output with the option -tavg
