gmx sigeps is a simple utility that converts C6/C12 or C6/Cn combinations to sigma and epsilon, or vice versa. It can also plot the potential in  file. In addition, it makes an approximation of a Buckingham potential to a Lennard-Jones potential.

Options to specify output files:

-o [<.xvg>] (potje.xvg)

xvgr/xmgr file

Other options:

-[no]w (no)
