Dear Chris and other %signal SPMers :-P ,
longtime ago I exchanged couple of e-mails with Paul Mazaika and I only
recently made my own version of the %signal change .. (well same version
as everybody in fact, there's only one way to compute it .. ) - this
version is a matlab / SPM like matrix one with a small formula to
compute the % - this page is located @
http://www.sbirc.ed.ac.uk/cyril/html/BOLD_percentage.html
