Hi freesurfer experts:
          1\ when I finished the first step of recon-all(-autorecon1), check with tkregister2, do i need to check each slice or I just need to check few key anatomicals (Anterior / posterior commissures, the temporal lobes in the coronal plane, and the midline cut)?  I think a lot of work to do so, and difficult to control. Is that necessary to do this for every subject?
          2\ when I finished fixing bad output from the talairachs registration, click the SAVE REG button, and I should rerun   : recon-all   -autoreon1 -subjectid  subjectname  or  next command ?
