I check the recon-all.log. It appears that the cortical region for caudalanteriorcongulate for this subject is very small..

table columns are: number of vertices total surface area (mm^2) total gray matter volume (mm^3) average cortical thickness +- standard deviation (mm) integrated rectified mean curvature integrated rectified Gaussian curvature folding index intrinsic curvature index structure name

That is a little strange. Can you look at the wmparc.mgz to see if it is there? Also look at the aparc+aseg.mgz to see how big the cortical region for caudalanteriorcingulate is. The wmparc is based on the aparc part of aparc+aseg. doug

I'm looking at stats/wmparc.stats, and there are some inconsistencies between subjects. I am wondering what might be the cause.

For one subject (say subject 1), part of the information appears to be:

# NRows 66 # NTableCols 10 # ColHeaders Index SegId NVoxels Volume_mm3 StructName normMean normStdDev normMin normMax normRange 1 3001 1869 1869.0 wm-lh-bankssts 101.6999 9.1445 69.0000 127.0000 58.0000 2 3003 1776 1776.0 wm-lh-caudalmiddlefrontal 98.1676 8.5074 75.0000 125.0000 50.0000 3 3005 710 710.0 wm-lh-cuneus 103.7088 10.1493 78.0000 134.0000 56.0000 4 3006 106 106.0 wm-lh-entorhinal 84.5902 9.0358 55.0000 96.0000 41.0000

For the other subject (subject 2), it appears to be:

# NRows 70 # NTableCols 10 # ColHeaders Index SegId NVoxels Volume_mm3 StructName normMean normStdDev normMin normMax normRange 1 3001 1012 1012.0 wm-lh-bankssts 93.6101 10.0971 71.0000 130.0000 59.0000 2 3002 1732 1732.0 wm-lh-caudalanteriorcingulate 104.3373 10.6871 58.0000 126.0000 68.0000 3 3003 4743 4743.0 wm-lh-caudalmiddlefrontal 95.2809 11.5139 66.0000 117.0000 51.0000 4 3005 1488 1488.0 wm-lh-cuneus 91.9310 10.1995 64.0000 126.0000 62.0000 5 3006 398 398.0 wm-lh-entorhinal 75.3343 9.0664 55.0000 101.0000 46.0000

Thus, in subject 1, there is no estimate for 3002, wm-lh-caudalanteriorcingulate, and the NRows is different.

Could you please help? Both are analyzed by FreeSurfer 5.1.0.

Thanks, Daniel
