GROMACS version: GROMACS/2023.3-foss-2022b-CUDA-12.1.1-PLUMED-2.9.2  
GROMACS modification: No  
Hopefully this is a simple question. I am running my own free energy analysis from simulations run with the pull code. I need to know if the following command returns the system total energy with or without the bias potential from the pull code:

`echo "Total-Energy" | gmx energy -f my_pull_simulation.edr -o my_pull_simulation_energy.xvg`

I would appreciate any insight here - thanks!

The potential energy includes the all potentials, also the pull bias potential (you can check by adding up the numbers).
