I am having trouble extracting values from a graph of the hrf curve and I
was hoping someone could help me out. Using Results and an SPM.mat file I
selected a T-contrast creating the glass brain image in the Graphics
window. Then I select "Cluster" and identify a coordinate point of
significant activation for this contrast. After this I select Plot ->
Event-related responses -> Fitted Response and 90% C.I. This generates
the hrf curve the 90% CI curves. I would like to extract the values that
SPM uses to plot this curve so that I can compare them more closely
between groups of subjects, but I cannot figure out how to do this. I was
unable to find any references to this in the mail list. In advance, I
appreciate the help.
