Hi Cat, first create and save a label of your cluster.
In a terminal, cd to the GLM directory inside qdec directory and then cd to the folder of the contrast of interest and run mri_segstats --id 1 --slabel fsaverage lh yourlabel --i gamma.mgh --sum yourlabel.sum the output yourlabel.sum will have information about the label including the mean gamma (gamma is a map of the contrast values).
Along those same lines, you can run
mri_segstats --id 1 --slabel fsaverage lh yourlabel --i y.mgh --avgwf yourlabel.dat y.mgh should be there already and is a stack of thickness maps for all your subjects the output yourlabel.dat will be a single column with the average thicknesses for each subject

Hello Experts: In qdec, I would like to analyze if the thickness- entorhinal volume correlation differs between APOE positive and negative subjects accounting for age. I have chosen age as a nuisance variable and entorhinal volume as a covartiate. ( hope this is correct) Results show me several clusters of group differences following FDR correction. Here is my question: I would like to know what the mean value differences are between the groups for various clusters. And I would also like to know which group shows less of a correlation for certain clusters. Could you tell me where I would find those values?
Best Regards, Catherine
