Fill holes in BOLD surface

Hi experts,

I have projected 4D-AFNI preprocessed BOLD data to Freesurfer cortical surfaces. Resulting individual surfaces have many holes (see attached image) that I would like to fill with nearest neighbors values around each hole (avoiding the medial wall). Could you indicate me how to do this?

Thank you in advance.


If values are projected onto the surface using something like 3dVol2Surf, you may want to use the -oob_value and -oom_value options to assign a value at those nodes. Also when viewing with suma, you may want to use the “shw 0” option in the surface controller.
