Thanks Daniel,
I was indeed using the original build of AFNI_2008_07_18_1710 -- I hadn't realized the versions change without a build number change. So, I have the -check function now.
If you could make the matlab script available for the cost function maps, that would be great.
Also, I noticed that the lpc cost function described in your paper is listed only under the hidden experimental options -- is this method still being tested and significantly altered or is it fairly stable now?
Thanks Again!
