Thank you very much Bruce!
Have a nice day/night.

The stuff outside the pial surface won't affect things, which is one of the reasons we prefer the surface-based measured of cortical morphometry.
Similarly, we don't use the surface-based stuff in the hippocampus, so you should be all set (since many of the cortical assumptions aren't valid there)
cheers Bruce

Dear Freesurfers!!
I've encountered two strange segmentation "errors", if they are errors at all.
Please see the attached fs.png:
You can see that there are excess pial tissues on the superior part of the brain. The pial surface is defined correctly and the excess pial tissue is outside the red line yet it is coloured pink. My question, is :
Does this have any impact on the results?
The second is related to the hippocampus.
Please see the attached fs2.png:
The pial surface around the hippocampus looks a bit weird. It actually discards 1/3 of the hippocampus (it is outside the red line).
Do you have any suggestions regarding the two problems.
I'm using FS 4.5 on several 64bit linux distributions.
