Hello Professor David,
Sorry for sending you a private email.
Thank you for your reply on forum. Is it possible to use external dipole
moment file which has" t Mx My Mz " data to calculate autocorrelation
function which is defined as phi (t) =  <M(t). M(o)>/ <M(0)>^2.
Autocorrelation file is necessary to use g_dielectric function.

Thank you.

Sincerely,
Bharat Sharma
