The Automated Functional NeuroImaging program is free software developed by Robert Cox, now at NIH. It runs as a freestanding program on a variety of Unix platforms. Both source code and binary executables are available for download. Note, however, that to go through our preprocessing tutorial, you'll also want programs that reconstruct and rename your raw files, a script to convert the afni files into MGH's preferred format (afnireg2bshort), the MGH programs and, to run the MGH programs, Matlab. For some of these files, go here. If you want to try afni out without worrying about all the other programs necessary for preprocessing, download the files from the Block Analysis area and consult the Block Analysis Tutorial.
