Hi,

We are trying to set up a freesurfer pipeline to measure cortical thickness for a multisite project. I came across the show-edits option in freesurfer 5.0.0. My understanding  from herehttp://surfer.nmr.mgh.harvard.edu/fswiki/Edits is that running show-edits  is supposed to give a edits.mgz file with regions where user intervention has been performed. I am not able to figure out why edits.mgz for a freesurfer output without any user intervention is still showing some regions(on the brain's edge approximately). Also, edits.mgz for a freesurfer output with user intervention, is able to show edited brain regions(great!!) with the unexpected persistent regions close to what were present in unedited freesurfer output. I am not sure if I am using/interpreting things the right way. Any suggestion on this will be highly appreciated.

Thanks,
Binod
