NAME

sigeps - convert c6/12 or c6/cn combinations to and from sigma/epsilon

VERSION 4.0.1

SYNOPSIS

sigeps -o potje.xvg -[no]h -nice int -[no]w -[no]xvgr -c6 real -cn real -pow int -sig real -eps real -A real -B real -C real -qi real -qj real -sigfac real

DESCRIPTION

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.
