Hi Antonella,
1. Can you load the lh.orig or rh.orig surface explicitly and see if it is
shown? Is the "orig surface" button clicked in the interface?
2. the hippocampus and amygdala are not neocortical structures and
shouldn't
be included in the surfaces (in fact, the surfaces in those regions are
somewhat arbitrary as they don't have the laminar architecture we are
expecting).
cheers
Bruce

Hi Bruce,
Thank again for your advice. I am not sure about the data collection but I will
find out soon. In the mean time I have two more questions:
1). The FS tutorial shows for the surface outlines (by loading the -surfs)
three line: the yellow indicating the white surface, the red for
the pial and a green line for the orig data. When I plot the surfs I have only
the yellow and red line. Can I get the green line somehow?
2). I suppose the two important brain structures, amygdala and hippocampus
must be included in the pial surface as a grey matter (I hope I am
right) .
If they are not enclosed in the pial surface is there a way to resolve this
issue? How I should edit the pial surface in this case? How
important is to have them enclosed for my cortical thickness studies and for
the GLM group analysi?
Thank you very much.
Antonella
