[Freesurfer] mris_make_surfaces scripts and how and when to use

Hello Freesurfer, I was going to the ReconAllDevTable ( https://surfer.nmr.mgh.harvard.edu/fswiki/ReconAllDevTable) and i came across 3 different mris_make_surfaces scripts. 1) When do I use any of the 3 mris_make_surfaces scripts after running recon-all -all? 2) Is there a default/standard nsigma above/below the mean to use when running the third mris_make_surfaces? 3) Which of the mris_make_surfaces can I use to correct the pial surface when it does cross the white matter and also, which is helpful with white matter surface extension? 3) Is this the correct recon-all script to use after wm edits with T2pial option? "recon-all -autorecon-wm -autorecon3 -T2 /T2_volume T2pial -s"

Thanks

Paul
