you don't have to - we will. You just draw it on the surface and tksurfer will figure out the volume coords and store them in the label file when you save it. You can then load it in tkmedit to see it in the volume if you want.

Thanks Bruce. How do I figure out where it should be in the volume based on
?h.white.surface ?

Hi Barnali,
it won't matter. If you run the subject through recon-all you can either
draw the label on the inflated surface, in which case we will automatically
figure out where it should be in the volume (based on the ?h.white surface),
or you can draw it directly in the volume. The surface is probably a lot
easier though.
cheers

Hi Bruce
Sorry for not being clear. let me explain.
My colleague has generated ROIs in 2 spaces using BrainVoyager. One is in
non-tal space, on inflated brain (AE_LH_INF.jpeg). The other is projected
onto TAL space,noninflated (AE_LH_TAL.jpeg). Both are attached here. Both
are essentially on the same subject AE, left hemisphere.
I need to draw ROIs in same location of inflated brain using tksurfer, on
same subject AE. I am not sure in which space, the inflated brain of
Freesurfer would be in. hence I want to know which one of the attached
pics
do I take as a reference when I draw the labels in Freesurfer
Thanks for your help

Experts,
I have some snapshots of ROIs made in BrainVoyager (in non-TAL space on
inflated brain, as well as ones projected onto TAL space).
I need to take the above as reference and make near-exact ones (ROIs)
using
Freesurfer on inflated brains. Which one of the above do I use as my
reference
