Have you run mri_glmfit-sim? It will create labels (ie, annotations) of the clusters as well as run mri_segstats to get means in each cluster for each subject. Try that link now doug

Hi Doug and FS team
I did glm analyses using mri_glmfit, and I was trying to plot the individual values in the population for a specific significant cluster. However I am not sure how to extract individual values from the entire cluster. (note that the concatenated surface used as input for the glm contains some 0 values that I want to exclude from the mean value of the cluster). Is there a way to build a label from a specific significant cluster?
Then, I was thinking about using mri_segstats --avgwf on the 4D concatenated file to get the average of the region but is there a way to not include 0 values?
And then I was also interested in getting the correlation coefficient from that same cluster, so maybe the script below would be helpful for that but I could not open it. ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/fast_glm_pcc.m
Thanks so much for your help Best Celine

Hi
I am trying to calculate correlation coefficient using freesurfer GLM for associations between volumes and IQ. I found this ealier answar, but the matlab script but the link appear to be dead.
