Hello freesurfer, 
I have several questions about mris_expand command. I know it can be used to expand or shrink a point on a surface by a fixed amount or distance. My questions are: 
1) Can it be used to expand the pial surface? if yes, please can you confirm if this is the right script= mris_expand -thickness rh.pial 0.5 rh.newpial. If the script is
wrong, please can you give me a directions on how to change it and what new flags to add. 
2) When I looked up mris_expand description, -thickness was the only flag displayed. Are there other hidden flags? If yes, where can I find them?
3) After expanding ?lh.white and ?h.pial, what steps of recon-all should i run in other to incorporate my changes? Thank you. 

Best, 
Paul
