[gmx-users] g_energy averages

[David L. Bostick]

HI,

I use g_energy on an edr file from a constant surface tension simulation.
I printed out Box-X, Box-Y, and Box-Z lengths and Press-XX, Press-YY, and
Press-ZZ pressures.  I am trying to fine tune a bilayer/protein system in
order to preserve the xy-area of the box.  I parsed the xvg file using a
simple awk script in order to calculate area, surface tension, average
pressures.. etc, but when comparing the values to those generated by
g_energy, there is a small discrepancy.  I am pretty sure I am calculating
things  correctly.  Does g_energy use some other precision for it's
calculation of averages and so forth?

David
