NAME
gmx-lie - Estimate free energy from linear combinations
SYNOPSIS
gmx lie [-f [<.edr>]] [-o [<.xvg>]] [-b <time>] [-e <time>] [-dt <time>]
[-[no]w] [-xvg <enum>] [-Elj <real>] [-Eqq <real>]
[-Clj <real>] [-Cqq <real>] [-ligand <string>]
DESCRIPTION
gmx lie computes a free energy estimate based on an energy analysis from nonbonded
energies. One needs an energy file with the following components: Coul-(A-B) LJ-SR (A-B)
etc.
To utilize g_lie correctly, two simulations are required: one with the molecule of
interest bound to its receptor and one with the molecule in water. Both need to utilize
energygrps such that Coul-SR(A-B), LJ-SR(A-B), etc. terms are written to the .edr file.
Values from the molecule-in-water simulation are necessary for supplying suitable values
for -Elj and -Eqq.
