Hi,
I have some problems about surface coordinates.
After running the qdec and analyzed my data(cortical thickness), I display a
plot of the data for a particular vertex by left-clicking on a point while
holding down the Ctrl key. It shows a plot and its plot window shows this
vertex's *surface coo
Hello all
I have some questions:
I would like to know how freesurfer computes the vertex’s wise areas? eg.
thouse in lh.area.
It should be expected that the sum of the areas of all the vertices across a
surface equals the total surface area?
To be much specific:
Can I compute the area of an
Hi Jorge,
yes, the area of a vertex is 1/3 of the area of all triangles that it is
a member of, and it should sum to the area of the surface. The average
subject has a correction factor that accounts for the "lost" area due to
averaging, so you'll need to apply this if you want it to be in tru
