gmx sigeps¶
Synopsis¶
gmx sigeps [-o [<.xvg>]] [-[no]w] [-xvg <enum>] [-c6 <real>]
           [-cn <real>] [-pow <int>] [-sig <real>] [-eps <real>]
           [-A <real>] [-B <real>] [-C <real>] [-qi <real>]
           [-qj <real>] [-sigfac <real>]
Description¶
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.
