Hello,

We have a large number of subjects processed with the default settings of 
recon-all. Unfortunately the presence of white matter creates problems when 
creating the white matter surface. There are large hypo-intensities in the 
white matter which badly distort the surfaces in multiple areas of the brain. 
It is unfortunate because these areas seem to have about the same signal 
intensity as true cortex, leading to a confused algorithm, and very pronounced 
segmentation errors.

I have been manually editing and reconstructing these surfaces, but the process 
is tedious and error prone. Are there any flags that might help recon-all 
perform better on brains with white matter pathology? Or otherwise things that 
I can do to make fixing the segmentation less painful?

Thanks,
Eli
