Hello,
Throughout most of Freesurfer’s version history, I
have noticed this problem pop up every 50 or so cases I do:
I will have a pretty well-processed surface but with some
inaccuracies in the WM surface, I will put control points down to correct it,
and reprocess with autorecon2-cp as usual. The surface comes back with the
areas I put CPs for accurate, but the rest of the cortex in a localized area
will have a massive amount of the surface missing. An example is attached as a
.png image.
Now, if I go back and put down control points throughout the
part of the surface that is missing after the first reprocessing and repeat
autorecon2-cp, the end result at that point is usually a perfectly accurate
surface. However, I was wondering if the massive loss in surface after the
first autorecon2-cp is attributable to some kind of bug that I might be able to
avoid.
Any thoughts would be great, thanks!
