What is your mri_segstats and mri_surfcluster cmds? The area computed from the triangles of the fsaverage subject are not representative of the average of the individual subjects that go into fsaverage. For this reason, we usually use the lh.area file inside of fsaverage to compute the area (this lh.area file is an average of the individual subjects). It may be that you are using both methods and so get different answers. dogu

I've noticed that if I run mri_surfcluster to produce a label file, then merge the labels into a single label using mri_mergelabels, then mri_segstats with the slabel option with the fsaverage subject; I get different surface areas from mri_surfcluster (summed all the cluster areas) and mri_segstats (1 area). Is there something wrong with my implementation of these three commands or is it expected that the two methods would produce different values?
