External Email - Use Caution        

Hi,

Although there are many ways to correct for pial, WM, and segmentation
defects, it seems common in the literature to forego any edits and simply
either accept or reject a subject's FreeSurfer output in order to avoid
subjectivity and potential over-editing. Another group rejected subjects if
their defects spanned 6 or more slices, for example.
Are there any guide lines on how much editing is too much editing? Should
it just be edited enough so it looks tolerable by eye? Maybe by a few
different raters?

The defects vary in their severity, so it's difficult to know if a subject
should be considered passable or requiring edits based on a minor defect.

My current plan is to conduct my analysis once with excluding subjects with
poor segmentation and then again, including  those subjects' edited
outputs. Do you agree with this logic?

Thanks for your advice,
Ryan
