Create a label of the cluster, then run
mri_segstats --slabel fsaverage lh /path/to/your.label --i y.mgh --id 1 --avgwf cluster.dat
where y.mgh is the file created by qdec in the qdec output folder and make sure to use the full path to the label. The output will be cluster.dat and it will have have a value for each subject. Does this work for you?

Dear Mailing List,
I have just completed a QDEC (v5.1.0) analysis of the following design: Measure: thickness Smoothing (FWHM): 10 Hemisphere: lh 2 Discrete (Fixed Factors): group (2 levels, AtRisk & Control) and gene (2 levels, CC & TTorTC) 1 Nuisance Factos: age
On completion of the analysis, I have selected the following results in the display tab: "Does the average thickness, acounting for group, differ between CC and TTorTC?". I have then completed an FDR correction by clicking the "Set Using FDR" (Rate 0.05) button. The following info is then printed to the terminal window: MRISfdr2vwth(): np = 163842, nv = 163842, fdr = 0.05, vwth=4.74798 Found 59 of 163842 vertices above FDR threshold (of 4.74798) I have then hit "Find Clusters and Goto Max" and found there to be a single cluster in the medialorbitofrontal, with a size of 26.09 mm2.
I would now like to know what the mean thickness is for that cluster at each level of my gene variable. How can this information be obtained?
