The MiniAOD data format - uwcms/FinalStateAnalysis GitHub Wiki
The MiniAOD data format was introduced by CMS in Spring 2014, and is intended to largely replace group-specific PATtuples. Thus if MiniAOD data is available and sufficient for your analysis, you will only need the Ntuplization capabilities of FSA. You should check out the branch miniAOD_dev, which has been modified for creating FSA Ntuples directly from MiniAOD EDM files.
