The first step in first-level analysis is the creation of an "analysis". The analysis is a collection of information about how you want to analyze the functional data. This includes the specification of the input data, event types, event schedules, hemodynamic model, nuisance regressors, etc. For FSL users, this is more-or-less the equivalent to running the Feat GUI. In FS-FAST, the work-flow is a little different that that associated with SPM or FSL. In those packages, you would specify all the analysis parameters *every* time you analyzed a data set. In FS-FAST, you do so once regardless of how many data sets you have.
