SPMers,
I have a simple contrast question. I have a paradigm wiht 3 conditions
(a, b, ab). If I set a contrast of -1 -1 1 does this show me the areas
where ab>a+b? If not what does this contrast represent?
I also have a programing question. When attempting to plot "contasts of
parameter estimates" I am not able to view or choose from all contrasts.
I have a data set with about 50 contrasts and I am only able to choose
from those that fit on the screen. If I type the contrast number, SPM
only allows me to enter 1-9. Is there any way to plot the data for
contrasts that do not fit in the window?
Thanks,
Paul Laurienti
