what was your command line?

Dear doug Using the command to only obtain the size of volume from every subject, however, I want to obtain the size of surface area from every subject, what should I do? thanks! Bo Xiang

Drawing the ROI as a label is fine. Just don't transfer the label
to each individual subject. The y.mgh is all the data for all the
subjects in the fsaverage space (where the label is defined). You
can use mri_segstats, something like

mri_segstats --i y.mgh --slabel fsaverage lh yourlabel.label
--avgwf avg.dat --id 1

avg.dat will have one column and number of rows equal to the
number of subjects

Dear doug
I am sorry to disturb you again, I still do not know how to
direct obtain the label of two significant clusters, is not to
draw the ROI? thanks!

Anyway, whether have command to direct obtain the label of two clusters, not to drawing the ROIs from these clusters, then there have exactly data to be obtained. Thanks!
