[Pw_forum] population analysis

[Seyed Javad Hashemifar]

It is not well clear whether your second run (parallel dimer) is correct.
In order to check the validity of the second run, check the spilling
parameters, whether they are small enough or not (I would say these
parameters should be less than 0.01)
