Dirk,
The SureFit algorithm is specifically designed for T1-weighted
volumes. I do not know if the SureFit algorithm can be adopted to
work with a T2 image.
If you have a manually generated segmentation volume, Caret can
reconstruct it into a surface. The SureFit Segmentation Dialog
allows one to start with a segmentation volume. In addition, there
is a Reconstruct Into Surface item on the Volume->Segmentation Menu.
If you have a reconstructed surface, in a format such as VTK, it can
be imported into Caret by using the File Menu->Import File Dialog.
Caret will read a few other surface formats which are listed on the
File Import Dialog.

Dear All,
We got a high-resolution (.15 mm) T2-weighted scan of a macaque brain
(gray matter brighter, white matter darker) and would like to
reconstruct the cortical surfaces and align it to a standard atlas.
Could this be done with any available software?
I had a look at the caret/surefit source code. Would you recommend
adapting the generateInnerBoundary / generateOuterBoundary /
generateSegmentation functions ?
Would there be an easy way of providing caret/surefit with a manually
segmented volume or reconstructed surfaces (from amira/itk-snap) ?
Thanks, -- Dirk
