+* `data` contains some resources data useful to create a database mimicking some real characteristics of the SNDS. 
+* `Data_Preparation` contains, on the one side, bash and python scripts used to set up files needed by the generator. On the other side, it contains a set of notebooks that details how the random distributions have been generated from the raw-public datasets
