 In virus crystallography, the 60 folds averaging is used to improve the
structure which obey the strict icosahedral symmetry. Because of the
crystal and symmetry averaging, the genome inside the virus is rarely
visible.

  I am wondering if someone could suggest a way to simulate the averaging
effect. If some real information is averaged with noise a couple of times,
or 60 times, what would the initial object look like after averaging.

  Thank you very much for your wonderful suggestion!
