Hi Amanda
it depends what you are doing. They will certainly distort thickness
estimates in those regions. It is really, really hard to get rid of dura
unless you acquire data for that purpose. If you have a highres FLAIR or T2
or a multi-echo mprage we have tools for automatically avoiding it.

Hi All,
I have noticed that almost all of my data has some voxels of dura that have
incorrectly been labelled as cortex. It doesn't look like a severe problem
and I've attached a screen shot to show you.
I'm just wondering whether this is something that will affect my results? I
have tried using -gcut and adjusting the watershed parameters to a height of
24, but nothing seems to work. As I have many subjects it would be very time
consuming to manually adjust all of these voxels.
Do you think this poses a problem or can I leave it as it is?
Best wishes,
Amanda
