AFNI: Software for analysis and visualization of functional magnetic resonance neuroimages

Abstract

A package of computer programs for analysis and visualization of three- dimensional human brain functional magnetic resonance imaging (FMRI) results is described. The software can color overlay neural maps onto higher resolution anatomical scans. Slices in catch cardinal plane call be viewed simultaneously. Manual placement of markers tin anatomical landmarks allows transformation anatomical and functional scans into stereotaxic (Talairach- Tournoux) coordinates. The techniques for automatically generating transformed functional data sets from manually labeled anatomical data sets are described. Facilities are provided for several types of statistical analyses of multiple 3D functional data sets. The programs are written in ANSI C and Motif 1.2 to run on Unix workstations.
