Dear FS experts, I have a doubt about inspecting white matter with free view. I could not find any irregularities where the blue line cuts through the surface. However, I noted in a few areas that the pail border makes funny shapes and seems to close up (please see attaches). I am in doubt here whether this should be edited or not. I have checked this in the other views and the inflated surface but I could not find anything wrong with the scan (eg.. a dimple or a hole). So I wanted to enquire whether I should consider this as a potential issue for editing. Also in the last attachment I have doubts about a yellow coloured in right parietal area apron. in the border between the white and pial. I was surprised of the location of this as the ventricles are usually yellow. It might be nothing but I just wanted to double check. Thank you! Pablo
Hi Pablo
in general the surfaces look quite accurate. Perhaps you could add some arrows to areas you have specific questions about? In general it's difficult to assess the accuracy of a surface from a single view though, so make sure you look at it in at least two orthogonal orientations. And don't worry about the surfaces in non-neocortical regions like the hippocampus/amygdala/ventricles. We don't use it there anyway.
cheers Bruce
