You can run something like the following: mri_segstats --slabel fsaverage lh $SUBJECTS_DIR/fsaverage/label/lh.BA1.label --i y.mgh --sum junk --avgwf avgwf.dat
y.mgh is created by qdec and should be in the qdec output. avgwf.dat will be a text file with a value for each of your subjects. This is the data you want (I think).

Hello Group,
We would like to create an ROI label in qdec and then run a correlation analysis with another factor to determine the relationship between thinning in the ROI and the measure of interest. Instead of looking at a single value from the ROI we want to look at the correlation across each vertex within the ROI. Basically we want to create a color map of the correlation within the ROI. Is this possible?
Thanks, Emily
