Hi,
I have a paradigm in which I show the subject 3 stimuli ( in block paradigm). I want to see the activation of each stimulus block and for that reason I have build three contrasts (say contrast 1 : positive stimulus 1 and negative stim 2 and stim 3; similarly contrast 2 and contrast 3). I want to overlay all the activations onto a single anatomical volume (in different colors) so that I can compare the locations of activations. Can I do it in FSFAST/Free surfer?
