Hi After the command, g_energy -f abc.edr -o abc.xvg the average values is printed out on the screen. Energy Average RMSD Fluct.

but the average values are different than calculation from the instantaneous data in the abc.xvg I sum up all the instantaneous data in the abc.xvg and average them. I got different average data as those shown up on the screen after g_energy command. How do the Gromacs get the average values, which shows up on the screen directly after the command g_energy?
