CIGAL, which stands for Compilable Imaging, Graphics, and Analytical Language, was originally designed for image processing and graphical reconstruction. However, most of CIGAL's features are not restricted to image-oriented tasks. CIGAL's language can therefore be used for a wide range of data manipulation or data analysis applications.
For fMRI, most applications use the Showplay program within CIGAL. Showplay is a package of CIGAL menus and scripts for presenting audiovisual or other stimuli, and recording behavioral responses. It features simple programming, flexible task design, and accurate real-time control.
