Hi all,
I'm using FS 5.0 and some time ago I was told by Bruce that I had to threshold the BA in order to have an approximate area when overlaying in the inflated surface. To get surface area values I also need to use the label_area and put a threshold having the possibility to choose the surface that I want, either white or pial.
But I can also get the BA stats in a table for all subjects and areas using either mris_anatomical_stats (on each label) or usinga script by Jamaan to get the table (since I already have the ?.BA.stats files), right?
My question is, which is the better/correct way to get the thickness and surface area values of the BA to export for statistical analysis since there are the thresolds issue.
I want to study mainly cortical thickness and surface area but also look also at the volume (which is surface-based, thus thickness*surface are will not be = volume since they are an average from each label, right?).
I' not sure of which approach to follow now... Does it depend on the measure I'll be using?
Thank you!
Andreia
