Hello Freesurfer experts,
I have come across a problem with several subjects in which the pial surface fails to adequately capture the anterior temporal lobes. This occurs despite accurate brainmask and wm volumes. I have included a screen shot below, in this case, the wm surface is also affected, but this is not always the case. This is pediatric data that was acquired on a 1.5T scanner and processed in Freesurfer v 5.3. The following expert options have been employed to try to improve surface rendering:
mris_make_surfaces -max_gray_at_csf_border 80 -max_csf 30 -min_gray_at_csf_border 35
Please let me know how I can solve this issue.
As a second question, I've heard that segmentation and surface rendering is improved with v 6.0, and I'm wondering if subjects that have been initially run through v. 5.3 and had manual edits made can then have autorecon run through v 6.0 for improvement of surfaces? Please let me know if this would be a reliable/recommended approach to improving surfaces.
Thank you, Meaghan Perdue
