I meant the glmfit folder, which is
lh.firstsessionscore1.glmdir

not sure what is happening. Can you tar up the glmfit folder and send it to me at our file drop?

Hello Bruce and Douglas, This is what my design looks like. GroupDescriptorFile 1 Class Group1 Class Group2 Variables Age Firstsessionscore Input subj1 Group1 72 0.76 Input subj2 Group1 67 0.43 Input subj3 Group2 80 1.23 The contrast matrix i used was [0 0 0 0 0.5 0.5]. I am writing to investigate if thickness correlates with the score removing the effects of group and age. The uncorrected map had blue and red colors in some areas of the brain. The blue color (thickness decreases withe score) seems unlike because i was expecting all red color(thickness increases with score). After I correcting for multiple comparison using 3 pos --cwpvalthresh 0.05, I tried to view the corrected map however, my entire left hemisphere was yellow with no clusters. how do i fix this?Thanks Miracle ________________________________________ From: freesurfer-bounces@nmr.mgh.harvard.edu freesurfer-bounces@nmr.mgh.harvard.edu on behalf of Douglas N Greve greve@nmr.mgh.harvard.edu Sent: March 24, 2016 6:36 PM To: freesurfer@nmr.mgh.harvard.edu Subject: Re: [Freesurfer] whole hemisphere is yellow
Can you give us more info about the design and the contrast you are testing? What does the uncorrected map look like?

I used 3 pos --cwpvalthresh 0.05 for correction. This displayed the precuneus area in yellow for one of my results however, for the other it displayed the entire hemisphere in yellow. Do I need to use the configure-- overlay? ‎Also, when I tried to view the cluster summary for the entire hemisphere results, I did not see a single cluster unlike, the cluster summary for the precuneus results

if it's all yellow it means everything is significant. What threshold are you using? On Thu, 24 Mar 2016, Miracle Ozzoude wrote:
Hello Bruce, No. This was after I ran the correction for multiple comparisons. Do I need to change the threshold too? My other results were fine. Thanks Best, Miracle

Hi Miracle
have you tried changing the thresholds? What kinds of values are you seeing?

hello doug, i performed a group analysis and after correction for multiple comparisons when i tried to load the corrected clusters the whole hemisphere was completely yellow. what should i do?
