Hi,
I have a quick and hopefully simple question. The picture on the left is an individual fmri mean functional display. To get it I used
Tksurfer-sess -hemi rh -aparc -s PROZ06004 -analysis simple_v_complex -c simple_v_complex while in /space/multnomah/3/users/gow/PROZ06/fMRI
The picture is "splotchy" whereas the second picture which is the average of all subjects for this same analysis and contrast is smooth and cleaner. In order to display the averaged data I used
Tksurfer fsaverage rh inflated -annot aparc -overlay group-analysis/simple_v_complex/rh.meanfunc.nii -fthresh 2 while in the same directory
I'm trying to get the individual subjects to look like the smooth averaged output. Can you help me with this? Thanks so much.
Best, Corey

Hi Corey,
you can try smoothing the individual data, but of course you won't have the power that you have in a group study (which is why you do the group study in the first place).

Do all the individuals look like that? How does it look in the volume?
