1.2. Downloading other/specific AFNI/SUMA software

1.2.1. Overview


If you are setting up your system for running AFNI, the main set of installation instructions for most operating systems is provided on THIS page.

Here, we provide direct links for downloading precompiled AFNI binaries, as well as the compilable source code.

As of Jan. 1, 2016, AFNI utilizes a version numbering system, which is useful for tracking changes, getting help on the Message Board, reporting in published work, etc. The version is reported using a trio of numbers, corresponding to “major.minor.micro” (or roughly, “yearly.quarterly.oftenly”) updates. You can discover the mystery number on your own system by simply typing:

afni -ver

This version number should always be provided when posting questions on the Message Board.


The record of changes (new options, new programs, bug fixes, et al.) is maintained for all the see in the online AFNI History.

Some additional introductory reading is available here.

1.2.2. To: update existing AFNI binaries

If you already have AFNI binaries working on your computer, all you need to do is run:

@update.afni.binaries -d

This will automatically detect which binary version to download and where to install it (based on location of the present binaries), and then it will unpackage the new binaries so you can just keep rollin’ along. (It will also make an automatic backup of your existing binaries in a subdirectory called auto_backup.BINARY_VERSION/, just in case you want it.)

1.2.3. To: download current precompiled AFNI binaries

If you don’t have AFNI on your computer already, or if you just want to download particular a set of binaries, then you can click on a link below to get the code for your desired system. Note that most Mac, Linux and even now Windows 10 users should look at The Authoritative HowTo for Installing AFNI instructions for simplest setups.

If you do decide to download binaries from links directly, you will likely still need to install supplmentary packages to run AFNI successfully. For help with that (and for seeing handy command line tools to check if things are OK), please see The Authoritative HowTo for Installing AFNI.

1.2.4. To: download the AFNI source code

Another way to get AFNI working on your computer (requiring a bit more work) is to compile from the source itself:

AFNI Source Code Compilable source (can be built on most Linux/Unix/Mac)

There are several usable, example Makefiles included in the main afni_src/ directory, as well as a couple (mainly for Linux systems) in afni_src/other_builds/.

In all likelihood this option is pretty much only useful if you are writing or contributing code yourself, or if your system is particularly finicky. Otherwise, it is likely far easier to grab a set of recommended precompiled binaries of the Linux/Unix or Mac variety.

1.2.5. To: browse all AFNI packages (and atlases)

The following is a browsable page that contains a tarball for each of the precompiled platform versions:

AFNI Software Packages

It also contains several standard reference brains and demo data sets. All files are downloadable by clicking on the links on the above page, and also by using command line functions such as curl or wget, such as:

curl -O https://afni.nimh.nih.gov/pub/dist/tgz/TTatlas+tlrc.*
wget https://afni.nimh.nih.gov/pub/dist/tgz/TTatlas+tlrc.*

NB: for most demo sets, there is an @Install_* command to procure and open the directory.
