Those are not important, just a few divots that did not get smoothed out during the inflation. The only thing that you need to be concerned about is the accuracy of the white and pial surfaces when viewed on the MRI volume. the inflated surface is only for visualization On 09/03/2016 10:22 AM,

no, I don't think it means that. It has more to do with the overall shape of the brain I believe, but we've never really investigated it On Sat, 30 Apr 2011, Tetiana Dadakova wrote: > Dear Bruce, Allison, > > Thank you for your answer. > > In tkmedit the surfaces look good. > Can this concavity

Dear Bruce, Allison, Thank you for your answer. In tkmedit the surfaces look good. Can this concavity mean that sulci are deeper in this region as compared to neighboring regions? I am not sure I understand how to interpret the inflated surface, therefore I cannot control if it is correct. Best

Nam, Are you using Linux Fedora Core and an NVidia graphics card? If so, then I have seen a problem where just a snippet of a surface is displayed in tksurfer. The solution is to upgrade the nvidia driver. You will have to go to the nvidia web site to get that driver. Nick > Hi all, > > I've
