[Chimera-users] Question reagrding potential energy value

Hello, I am using the minimize structure tool under structure editing. I am using this tool because I would like to compare energies for a WT and a mutant structure (point mutant). I am getting potential energy value in the reply log. I wanted to check with you is there is a unit that I can use for that potential energy. I also would like to know if this means that the higher potential energy value means that the protein is less stable. Foe example, the potential energy for the WT is: 3132.577437 The potential energy for the mutant is: 2858.355152 So that means that the mutant protein has a lower energy and is more stable, right? Thanks you, Marie
