[Freesurfer] Question regarding missing pial surface

Hi,

I have been working on segmentation of brain scans using Freesurfer and I came across a few scans in which the pial surface does not extend all the way. I have attached two screen shots of the problem I have been encountering. Any suggestion to resolve this kind of error is appreciated.

Thanks,
