Hi there,
Recently, I use FreeSurfer analyze a clinic data, the result show a very thin cortex layer, (see figure. 1). I load the wm,mgz (see figure.2), and then overlay the segmentation results, (see figure. 3). As you can see, part of wm.mgz around the wm mask boundary are classified as gm, I guess this is because of partial volume.
My question is if I use a better wm mask to replace freesurefer's brainmask (see figure. 4), could I get a better result?
Thanks! Guang
