AFNI (Analysis of Functional Neuroimages) is a package of computer programs for analysis and visualization of three-dimensional human brain funcational magnetic resonance imaging (FMRI). It can color overlay neural activation maps onto higher resolution anatomical scans. Slices in each cardinal plane can be viewed simultaneously. Manual placement of markers on anatomical lanmarks allows transformation of anatomical and functional scans into stereotaxic (Talairach-Tournoux) coordinates. Facilities are provided for several types of statistical analyses of multiple 3D functional data sets. The programs are written in ANSI C and Motif to run on Unix workstations.
