Hello again, My questions refer to the attached image. The image is of the average subject I created from our subjects using the "make_average_subject" command. As you can see, in an inflated view there are many gyri and sulci looking structures that shouldn't be there. Clearly something is not right.
My first question is what aspect of our subjects' brains could be causing this? I have inspected the brains in tksurfer and have not found any defects that could account for this.
My second question refers to the oddness at the bottom left of the image. That is something I notice happening all the time. Everytime I drag any window across the tksurfer or tkmedit window that happens. It goes away once I rotate the brain or zoom in or out or anything like that. Is this something that people have encountered before or is this an anomaly unique to our system?
Once again, I really appreciate any help these matters.
Thank you, Devdutta
