Hi,
In the main output file geometry optimization, at the end of geometry
optimisation step, I have the following information:
-------- Informations at step = 53 ------------
Optimization Method = CG
Total Energy = -94.0112708604
Real energy change = -0.0000036472
Decrease in energy = YES
Used time = 343.953
Convergence check :
Max. step size = 0.0006162087
Conv. limit for step size = 0.0010000000
Convergence in step size = YES
RMS step size = 0.0002737159
Conv. limit for RMS step = 0.0010000000
Convergence in RMS step = YES
Max. gradient = 0.0005305121
Conv. limit for gradients = 0.0010000000
Conv. in gradients = YES
RMS gradient = 0.0002356500
Conv. limit for RMS grad. = 0.0010000000
Conv. in RMS gradients = YES

Now my question is:
Which total energy i have to use for my data?and why this two total energy
that with yellow color is different?
Thanks in advance.
