  We present a Generalized Effective String Rope Model (GESRM) for the
description of the initial state of relativistic heavy ion collisions. We start
from the Effective String Rope Model (ESRM) and take into account fluctuations
in the initial state following the Glauber Monte Carlo approach. Results from
symmetric Au+Au collisions at different impact parameters and asymmetric A+Au
head on collisions are presented at RHIC energies. The produced initial state
is used as an initial condition for further hydrodynamical calculations.
