WebDescription ¶. gmx energy extracts energy components from an energy file. The user is prompted to interactively select the desired energy terms. Average, RMSD, and drift are calculated with full precision from the simulation (see printed manual). Drift is calculated by performing a least-squares fit of the data to a straight line. http://www.mdtutorials.com/gmx/lysozyme/09_analysis.html
