Hi all, I'm having trouble with V1 labels that are mapped automatically in freesurfer. I've noticed that there are holes in the label when I load it onto a 3d brain in tksurfer. This happens more often for the left hemisphere and not so much for the right. I've found the problem persists even after doing manual edits of the borders and fixing the brain extraction. I was just wondering if anyone has had the same problem or knows how to fix it (see message previously posted below).
Thanks! Hi Doug, Sorry it's been a while since I've ran the initial codes, but I think these are the labels automatically generated by Freesurfer v5.0 during recon-all (correct me if I'm wrong). Here's what I ran below: recon-all -all -notal-check -cw256 -force -subjid MB18 -i ~/Desktop/New_CT_niis/MB18.nii.gz then recon-all -force -s MB18 -qcache -i ~/Desktop/New_CT_niis/MB18.nii.gz I've checked a few more brains and noticed the same problem. I've also noticed that the left hemisphere is always worse than the right. When opening the brains in tkmedit, the labels are not continuous on the surface. Could this be the problem? Is this label the same as the Hinds label and if not, should I run that instead? Is possible to edit the label, and if so, how often does one have to edit the labels automatically created by freesurfer? I know that too much editing can take away from the standardization of the process and I wouldn't want to mess with that too much. Thanks!
