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

Analysis question

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
