Hi Doug, I finished running FSFAST on fmri data set. I corrected the data for multiple comparison.In order to visualize the results I ran the following command line:
tksurfer fsaverage lh inflated -overlay cache.th30.pos.sig.cluster.nii.gz -annot cache.th30.pos.sig.ocn.annot -fminmax 1.3 3 I attached two figures (figure 1 is for two groups and no covariates; Figure 2 is for OSGM) from the output of this command line: My questions are: 1. I understood from figure 1 that the yellow color is the annotation's color which survived after correcting the results for multiple comparison. Is this correct? 2. What are the green and magenta colors means ( the lines around the yellow color)? 3. For some cases I noticed that after correcting for multiple comparisons I have one or two significant annotations in the file "cache.th30.pos.sig.cluster.summary" but when I ran the previous command line I see the yellow color is covering wide areas of the brain like how it looks like in figure 2. So how can I explain that? Is it related to something wrong in the analysis? Thanks Mohamad
