Hi, 

     I am a relatively new user of Freesurfer and have a couple questions.  I have gone through the tutorials and I am now at the point where I check the segmentation.
If I open my subject in tkemdit (tkmedit your_subject_name brainmask.mgz -surfs -aseg)  and use the edit the segmentation and then press "save segmentation", I am editing the aseg.mgz file, correct?  After doing that, what parts of recon-all would I need to run again?
Thanks,
Maria
