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

It's not unusual to have asymmetries in some patients. 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.
