NAME
       gmx-sigeps  - Convert c6/12 or c6/cn combinations to and	from sigma/ep-
       silon

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  combina-
       tions  to sigma and epsilon, or vice versa. It can also plot the	poten-
       tial in	file. In addition, it makes an approximation of	 a  Buckingham
       potential to a Lennard-Jones potential.

OPTIONS
       Options to specify output files:

       -o [<.xvg>] (potje.xvg)
	      xvgr/xmgr	file

       Other options:

       -[no]w (no)
	      View output .xvg,	.xpm, .eps and .pdb files

       -xvg <enum> (xmgrace)
	      xvg plot formatting: xmgrace, xmgr, none

       -c6 <real> (0.001)
	      C6

       -cn <real> (1e-06)
	      Constant for repulsion

       -pow <int> (12)
	      Power of the repulsion term

       -sig <real> (0.3)
	      sigma

       -eps <real> (1)
	      epsilon

       -A <real> (100000)
	      Buckingham A

       -B <real> (32)
	      Buckingham B

       -C <real> (0.001)
	      Buckingham C

       -qi <real> (0)
	      qi

       -qj <real> (0)
	      qj

       -sigfac <real> (0.7)
	      Factor in	front of sigma for starting the	plot
