Abstract We have developed an autonomous script that helps the user to automate the XMM‐Newton data analysis for the purposes of extensive statistical investigations. We test this approach by examining X‐ray spectra of bright AGNs pre‐selected from the public database. The event lists extracted in this process were studied further by constructing their energy‐resolved Fourier power‐spectrum density. This analysis combines energy distributions, light‐curves, and their power‐spectra and it proves useful to assess the variability patterns present is the data. As another example, an automated search was based on the XSPEC package to reveal the emission features in 2–8 keV range. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
