[Freesurfer] Editing after reconstruction

Hello FS-ers,

I have a beginner question.

I am wondering about editing. Since I have no superior of me in my lab to inspect or guide me in my freesurfer analyses - I get a bit worried that I might oversee some important errors from recon-all.

If there is nothing that is strikingly wrong in the output from recon-all - should I then expect my results to be good enough for group analyses?

If there is no error messages, and nothing that looks strange when I open rsults in tkmedit (for a beginner)?

How often does a reconstruction from Freesurfer need to be edited,(roughfly, on average) if you have a group of lets say 32 subjects ?

thank you so much for your help!

best regards, Cris
