  The XENON100 experiment, situated in the Laboratori Nazionali del Gran Sasso,
aims at the direct detection of dark matter in the form of weakly interacting
massive particles (WIMPs), based on their interactions with xenon nuclei in an
ultra low background dual-phase time projection chamber. This paper describes
the general methods developed for the analysis of the XENON100 data. These
methods have been used in the 100.9 and 224.6 live days science runs from which
results on spin-independent elastic, spin-dependent elastic and inelastic
WIMP-nucleon cross-sections have already been reported.
