Try this paper: Drury, H.A., Van Essen, D.C., Anderson, C.H., Lee, C.W., Coogan, T.A., and Lewis, J.W. (1996) Computerized mappings of the cerebral cortex: A multiresolution flattening method and a surface-based coordinate system. Journal of Cognitive Neurosciences 8: 1-28 http://brainvis.wustl.edu/resources/Drury_JCN96.pdf I'm not sure how this source got here, but it does pretty closely resemble a snapshot of that file I had lying around: http://caret.sourcearchive.com/documentation/5.6.4~dfsg.1-1/BrainModelSurfaceCurvature_8cxx_source.html This is not a fast-changing part of the source, so it stands a good chance of being how caret does it. Does anyone know how caret source got in sourcearchive.com? I know our source is open, but I don't know who was nice enough to put it there, or how often it is updated. > > Kind regards, > > Lisa Ronan > > Research Associate > Brain Mapping Unit > University of Cambridge > UK > > > _______________________________________________ > caret-users mailing list > [email protected] > http://brainvis.wustl.edu/mailman/listinfo/caret-users _______________________________________________ caret-users mailing list [email protected] http://brainvis.wustl.edu/mailman/listinfo/caret-users
