Hi All,
I have been using SPM for now quite long ... but I have come across a
"simple" problem for which I was not able so far to find a solution:
I need to compute a set of contrasts (as usual! :-) ) but I want that
only POSITIVE betas are considered. That is I want to include in the
analysis only voxels showing activation BUT NOT deactivation patterns.
Is there a "simple" way in SPM for doing that and, most important, is
there any way to script the procedure?
Thanks a lot in advance for any suggestion that might help to solve this
problem.
Best, Antonino Casile
