Hi Bruce

I am new to freesurfer and im having a few issues with a number of my scans.  The cerebellum and sections of the occipital lobe seems to be cut off on a number of subjects, so i went in and altered the skull stripping by increasing the watershed threshold to 35 and using -no-wsgcaatlas.  When i review the scans afterwards, the pial and WM surfaces haven't included the original missing sections of the scans.  How do i go back and include these missing sections?

I have attached a screenshots.

Thank you kindly

Julia
