Bruce
I understand your point. I think I could try to do some test in order to know if the results are affected too much. I'm going to tell you my conclusion once I get it.
Can you tell me what are these tools you mentioned?

Hi Guido
all automated algorithms have failure modes, so you are always advised to look at the results to make sure that they aren't artifactual. We have some QA tools that makes this process less onerous if you want. You can certainly run in an automated fashion, but then you won't know for sure if the results you found were due to an algorithmic artifact or the real biology
sorry Bruce

Bruce, thanks for your reply
My goal about cortical morphometry is measure the mean thickness of some areas. Do you know if these pieces can mess up the pial surface enough to affect the mean thickness? I ask you about it because I am trying to avoid operator control on the process, I want to make it automatically.
Being all for now, I await a reply

bits of dura or skull that are left by the skull stripping don't matter *unless* they mess up the surfaces in the vicinity (e.g. by being included in the pial surface or creating topological defects that are incorrectly fixed). cheers Bruce On Thu, 19 Nov 2015, Guido Orlando Pascariello wrote: Hi Experts I'm using Freesurfer to quantify some subcortical volumes and cortical areas. I have been preprocessing my data using 'recon-all autorecon1' I have a question About Skullstripping. It is leaving a little bit of dura behind the head. I found '-gcut' which is useful to solve it but it has some cons. I don't want to view the data, I just want to get the quantifications, so I wonder if this pices of dura could affect the '-tessellate' step.
