[Freesurfer] Editing brain.finalsurfs.mgz

Dear experts,I am trying to fix the surfaces which are crossing to each other in the middle where the hemispheres reach each other.As Bruce mentioned before I am trying to create two volumes (lh.brain.finalsurfs.mgz  , rh.brain.finalsurfs.mgz ) nad edit them individually.Then I want to rerun this command for each hemi:mris_make_surfaces  -subjid <name>     -whiteonly -noaparc -mgz -T1  lh.brain.finalsurfs   lh  mris_make_surfaces -subjid <name> -white NOWRITE -mgz -T1 lh.brain.finalsurfs  lh  Am I using the correct command?What should I expect to have after running this command line(for example first one)?Sould I rerun (recon-all -autorecon-pial ) after all? Thanks in advance for the help, Maryam
