Hi Steve, this is Eric Feczko. I have just started using FSL and I have a couple
of questions concerning the results that FEAT produces and a question about the
setting up the design matrix. In our study, a subject is presented with a series
of faces for which there are seven conditions: happy, sad, fearful, neutral,
angry, suprise, and disgust. We run the experiment four times on the subject,
and each run's timing for the presentation is different. Since FSL can only
analyze more than one subject when the timing is the same for all runs, should I
cocatenate all the runs together and then analyze each subject, or can I just
analyze each run separately, and then do a group analysis combining all four
runs for each subject? I also have two questions about the results. First, how
can I acquire all the data from each voxel cluster? And second, I noticed that
all the .GIF files were sliced from a coronal view. Is there a way to reslice
the images produced by FEAT from different orientations? If you can provide any
help in this matter that would be great, thanks!
-Eric
