%-- Script to be used as an example to evaluate the quality of the reconstructed images

%-- After choosing the specific configuration through acquisition_type, 
%-- phantom_type, data_type and flag_display parameters, this script allows computing the 
%-- chosen evaluation metrics.

%-- By default, the computed metrics are saved in a text file in the folder named "evaluation"
