Hi everyone, I'm a very new fresurfer user and I have to understand the very simple basis of its use yet. So I have some maybe stupid questions about that. I heve to work on cortical thickness, so I suppose I have to complete the segmentation and then correcting CPs and Pial surface. The first question is if I have to edit CPs first and then, after running recon-all -autorecon2-cp -autorecon-3, to edit the Pial surface? The second is in the CPs editing have I to add ctrl pts in white matter areas that are less then 110 in voxel intensity? The last one is how do I have to correct the grey matter? Have I to paint all the None Sgmtn label points, or just the ones incorporating a piece of dura? Thanks a lot, and sorry for the very basic questions. Claudia
