You have made several mistakes. First:
set path = '~/abin/afni'
should be instead
set path = ( /root/abin/afni/ $path )
If you are using the C shell. If you are using the Bash shell, then instead
export PATH=/root/abin/afni:$PATH
is what you need.
When you run the "afni" command, nothing is failing -- the program starts. But you have no data in the directory where you started AFNI. Instead, you should "cd" to a directory with some AFNI-formatted data and try the program there.
