The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to determine the effective electron anti-neutrino mass in a model-independent way by investigating the energy spectrum of tritium beta-decay electrons near the endpoint with a sensitivity of mν=0.2 m_\nu = 0.2 eV/c2 ^2 (90% C.L.). The detector of the KATRIN experiment is segmented into 148 pixels, each measuring an independent β \beta -spectrum. Additionally the spectrum will be measured several thousands of times. The data of each pixel and each measurement must be combined to retrieve the effective electron anti-neutrino mass. This poster will present strategies for the high-level analysis of the KATRIN experiment including a proposal of how to combine the different data sets and presumably the results of the analysis of first KATRIN data.
