I am trying to understand what happens if I go in and edit the numbers for -min_border_white  -min_gray_at_white_border  in a single subjects in a large group.

Generally we aim to set everything identical when running a group of subjects in FS.  I went in and had a look at the recon-all log file and I can see that the numbers for -min_border_white  -min_gray_at_white_border  different for different subjects.

Thus - what will happened if I go and edit the -min_border_white  -min_gray_at_white_border numbers for  a single subjects in a large bach .... will I still be able compare cortical thickness with subjects that I did not edit?

Or is it necessary to keep the number identical for all subjects when editing the min_border_white  -min_gray_at_white_border
