  Hallo to all
I try to use the function g_dielectric but it does not work , before 
I use the function g_dipoles to create the ACF of the all system it 
is the dipcorr.xvg and I put it as the input  file for the 
g_dielectric  but I obtained a message of error, I 'd like to know 
which is the correct file format or input file that I have to give to 
the g_dielectric to get results. (I try with the exmple of methanol 
and peptide in the gromacs share directory).
Thank you Caterina


this is the type of the error that I obtained.
