Hi Jose,
If you're using Freesurfer 4.5, the aparcstats2table program has a known bug that causes the columns to be written in a random order. Depending on how you create a database from these files, it could lead to what looks like a large asymmetry, when really you're just comparing columns from different regions.
Best, Mike

I have seen some myself in AD. Have you checked the segmentation in those areas?

Hi all,
I am doing a study about the medialorbitofrontal, and I am having some strange area results in a lot of subjects.
The rh areas are much higher than the lh areas of medialorbitofrontal: Some examples:
lh rh 1714.0 2822.0 1720.02632.0 1728.0 2675.0 1877.02733.0 1498.0 2719.0 2067.02542.0 1870.0 2666.0 1554.02263.0 1535.0 2566.0 1794.02392.0 1487.0 2547.0 Why is this happening, any idea? Should I do any correction?
Thanks for the help,
Miguel.
