11:32:04	 From Emmanuel Nezri : Thank for this nice talk.
Sorry I cannot take the floor orally, bad connexion.
Can we say that such codes is (will be?) able to identify the lagrangian volumes of halos/structures only by reading the density field or the mass distribution of the ICs ?
11:34:42	 From rlenoble : Hi, thanks you ! 
I did't understand how this technique is a plus compared to standard N-body code because you can also test the effect of an isotropic mass distribution with standard N-body code
11:36:39	 From rlenoble : ok, thanks you !
