Assumption(s):

    The computer's operating system should be a recent release of Linux,
    i.e. at least as new as Red Hat 8.0, Mandrake 9.x, etc.

    The commands listed below assume that the user is running the T-shell
    (/bin/tcsh).  This makes a difference here only when setting the path,
    but in general, /bin/tcsh is recommended over /bin/bash.

    To change the shell to /bin/tcsh, see notes: change the shell

    To set the PATH under /bin/bash,  see notes: set the PATH in /bin/bash

Description:

    There are basically 5 steps to installing and running AFNI.  The
    commands associated with these steps can be entered into a terminal
    window.  For a user with very modest experience, it may be best to
    copy-and-paste the commands into a terminal window, rather than to
    type them in.  If a typo is not noticed, or not understood, it can
    be difficult to figure out how to correct the problem.

----------------------------------------------------------------------

AFNI: download and install

    Step 0: enter these commands to prepare for installation:
	    
	    cd
	    mkdir abin
	    

    Step 1: enter these commands to get and unpack the AFNI binary package:
            (set package to linux_xorg7 if you prefer that to linux_gcc32)
            (note: this step can be repeated to update your AFNI binaries)
	    
            set package = linux_gcc32

	    wget http://afni.nimh.nih.gov/pub/dist/tgz/$package.tgz
	    tar xvfz $package.tgz
	    mv $package/* abin
	    rmdir $package
	    

    Step 2: enter these commands to get and unpack some sample data:
	    
	    wget http://afni.nimh.nih.gov/pub/dist/edu/data/AFNI_data3.tgz
	    tar xvfz AFNI_data3.tgz
	    

    Step 3: enter this command to add the directory ~/abin to your path:
	    
	    echo 'set path = ( $path ~/abin )' >> ~/.cshrc
	    

    Step 4: log out and log back in


    Step 5: open a new terminal window, and start playing!
	    
	    cd AFNI_data3/afni
	    afni
