Recent spectral and spatial X-ray observations of galaxy clusters suggests subclustering and merging in many clusters.Hence galaxy clusters can be grouped into two categories; relaxed and non-relaxed clusters.We have investigated the use of six morphological parameters (Gini, Asymmetry, M_{20}, Concentration, Ellipticity, Smoothness and Gini 2nd order) to differentiate between relaxed and non-relaxed scenarios.We initially simulated different relaxed and non-relaxed morphologies with multiple beta profiles and then also simulated these clusters for Chandra observation using the MARX simulator software.Finally,we applied our method to a different redshift sample of clusters from the Chandra archive. In this talk I will present the promising results from the six morphological parameter calculations.
