In QDEC, there is not a way to do this, but you can do it from the command line. If you cd to where the qdec output is (it might be a folder called Untitled in your $SUBJECTS_DIR), then run
mri_glmfit-sim --glmdir Untitled --cwpvalthresh .05 --cache 1.3 abs --2spaces
This will only take a minute or so to run. In each contrast folder, there will be a file called cache.th13.abs.sig.cluster.summary with a list of clusters and a file called cache.th13.abs.y.ocn.dat which will have a column for each cluster and a row for each subject. You can compute statistics from this.
Note that the clusters found this way should be the same as with qdec, but might not be if the threshold parameters are not identical.

Dear surfers. I’ve analyzed 2 group comparison data using qdec gui. I got some significant clusters after Monte-carlo simulation with 1.3, absolute. However, I have no idea to get thickness value of each group in the significant areas.
Is there any way to extract mean (and S.D. if possible) thickness of the area shown in gui analysis after monte-carlo simulation?
