Kevin,
It's hard to tell what could be causing this; my first guess would
be image data problem. Did an equivalent parametric analysis run OK?
You might try
load SnPM_cfg
load SnPM
if (~bhPerms); MaxT=MaxT(:,1); end
hist(MaxT(:),40)
This will give you a plot of the permutation distribution. If it's just a
bar at 0, then it would seem that you have all-zero data. Let me know
what it looks like otherwise.
