Try g_energy to extact the energies from your original runs. 
Alternatively, you may re-calculate them from the trajectory using mdrun 
-rerun.

You can use trjconv on the trajectory with 'collected conformations', to 
set the timestep between frames to 1 ps, that way, frame number and time 
will be the same.
