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. This program only configures the analysis; it does not analyze the data.Setting up analysis is only done ONCE, and then it is applied to any and all sessions.
The First-Level Analysis (FLA) consists of:
- Setting up models of the task-related components
- Setting up models of the nuisance components
- Defining contrasts
Configuring the FLA is performed with mkanalysis-sess -gui
