Has the instructions (there's also a link to that page at the top of the
AFNI Phorum Message Board). Let me know if you have any questions.
Make sure you send at least one header/datafile pair, and maybe a
text file with a complete description of the scan in that file, or you could
just e-mail or post that description.
