Hi Lena, in general you only need to fix the skull stripping if it makes any of the downstream processing less accurate. If the surfaces and aseg in the region where the skullstrip leaves are accurate than you don't need to do anything.

Hi all

I am not grasping the concept of skull strip correction full, Im afraid. I have attached a brainmask ­ 128th slice sagittal of which shows some uneven stripping (I couldn¹t attach the huge T1 image to overlay) - is this degree of tissue separation acceptable?

Where does one set a limit? The example set in tutorial data shows some very obvious stripping errors, but the data I have shows really minor stuff ­ and I am always unsure whether to continue auto recon 2 or correct them. Any help?

Many thanks in advance

Cheers LKP
