# 3. Installing AFNI (software)

To install AFNI, please see HowTo #0 for descriptions and details.

For help with installation difficulties, please search or post to the AFNI Message Board

If you are somewhat confident, consider this quick example for a modern Linux system:

    curl -O http://afni.nimh.nih.gov/pub/dist/tgz/linux_openmp_64.tgz
    tar xfz linux_openmp_64.tgz
    mv linux_openmp_64 ~/abin
    echo 'set path = ( $path $HOME/abin )' >> ~/.cshrc
    source ~/.cshrc

Alternatively, consider this quick example for a general system:

    curl -O http://afni.nimh.nih.gov/pub/dist/bin/linux_openmp_64/@update.afni.binaries
    tcsh @update.afni.binaries -defaults
    echo 'set path = ( $path $HOME/abin )' >> ~/.cshrc
    source ~/.csrhc

To update an existing AFNI installation, consider simply:

    @update.afni.binaries -defaults

After this is done, it may be necessary to open a new terminal window.
