[Freesurfer] Very strange error in surface reconstruction after a2-cp

Dear FS experts,

I have a very strange error after running autorecon2-cp. I never saw this kind of error with previous versions of FS. I run recon-all -all on my subject, and obtained very good surface reconstructions, with the exception of few excluded wm voxels (see attachment called "before autorecon2-cp"). I added few control points throughout the entire image (for a total of 20 control points) and I run -autorecon2-cp -autorecon3 on the same subject. The output I obtain is very bad (see attachment called "after autorecon2-cp"). How is it possible that adding 20 control points causes such a surface distortions?!!

I never had this error with previous FS versions.

Thank you for any suggestion.

Kind regards,

Paola
