Hey everyone. Im looking to run g_dielectric on my total dipole moment ACF (dipcorr.xvg) by:

g_dielectric -f dipcorr.xvg

I get the following error message. Does anyone know what parameter they are referring to?

WARNING: non-polarizable models can never yield an infinite
dielectric constant that is different from 1. This is incorrect
in the reference given above (Spoel98a).
