Dear users,

I have a simulation, and performed rerun for extracting energy terms. When I use gmx energy there are only few terms appear as follows:

1 Bond 2 Angle 3 U-B 4 Proper-Dih.
5 Improper-Dih. 6 LJ-14 7 Coulomb-14 8 LJ-(SR)
9 Disper.-corr. 10 Coulomb-(SR) 11 Coul.-recip. 12 Potential
13 Box-X 14 Box-Y 15 Box-Z 16 Volume
17 Density

How can I get total energy of system? I could not find kinetic energy term?
Is it need to use gmx traj for trr file?

I guess this in an energy file from an energy minimization, not an MD simulation.
