I need to calculate the auto-correlation function (ACF) of total dipole
moment of Methanol box.
I obtained the total dipole moment from VMD and calculated the ACF manually.
However, this gives negative values.
In the selection tab i selected "all" the molecules. I didn't change the
scale or radius.
Do these things affect the total dipole moment.

Thank you.
