afni.nimh.nih.gov

I think I would try to download and extract afni inside vector linux. If vector has wget this is one way to do that:

cd /software/afni

mv /software/afni /software/afni.old

wget [afni.nimh.nih.gov]

tar xvzf linux_xorg7_c4.tgz

mv linux_xorg7_64 afni

If vector doesn't have wget, you may be able to use curl instead of the wget command:

curl -o linux_xorg7_64.tgz [afni.nimh.nih.gov]
