Sorry, but could you tell me the meaning of the Average value that comes
from g_dipole and also how you calculate the dipole of a charged system
with g_dipole? Do you calculate the dipole wrt the center of mass of the
system, a geometrical center or maybe something else?

My protein has a total charge of +12.

Thanks, Carmen
