Hi Doug, Thank you very much for your output about my output files. Yes, I understand that these images are skull stripped. But since there are possibilities of error in the skull stripping process I was concern about extra no brain tissue being included in the output. I think the location of the tissue I was referring was mistaken. To make it clearer I have circled (in red) the specific area in the images attached I have concerns about not being brain tissue. I noticed that this repeats in several other of my subjects and I wanted to make sure it is fine. Best,Pablo

Hi Pablo, this is a skull stripped image. In the human brain there is no brain tissue ventral to the orbital frontal areaso any tissue there has been stripped away. doug

Dear FS experts, I have a doubt about a potential registration problem after running recon-all -all. I noticed that one of the image outcome when opened with tkmedit shows no-brain tissue (perhaps eye tracts) ventral to orbitofrontal areas. I have attached snapshots to illustrate the image. I would greatly appreciate your output on this since I have no experience with FS and I am not sure what to expect. I would like to enquire whether I should be concerned about this image or if this is not a problem.
Many thanks, Pablo
