AFNI is a set of C programs for processing, analyzing, and displaying functional MRI (FMRI) data - a technique for mapping human brain activity. It runs on Unix+X11+Motif systems, including SGI, Solaris, Linux, and Mac OS X. It is available free (in C source code format, and some precompiled binaries) for research purposes.

• AFNI is free software, and comes with no warranty or guarantee. There is no assurance that it works as documented, that it does anything remotely useful, or that it won't cause actual damage to the structure of the Universe.
• The conditions for use and redistribution of AFNI are listed here.
• The software changes frequently; if you use the AFNI package, you should read the Latest News Page or the SSCC Blog regularly to keep up with recent changes.
• If you have questions, it is better to post them on the AFNI Message Board than ask via e-mail.
