The SureFit algorithm is complex algorithm that identifies the cerebral cortex. It is described in "Van Essen, D.C., Drury, H.A., Dickson, J., Harwell, J., Hanlon, D., and Anderson, C.H. and (2001). An integrated software suite for surface-based analyses of cerebral cortex. Journal of American Medical Informatics Association . 8:443-459". This paper can be downloaded from "http://brainvis.wustl.edu/wiki/index.php/Lab:Publications " or http://www.jamia.org/cgi/content/abstract/8/5/443. If you are unable to get the full text version, I can make a PDF version available to you, just let me know.
The "Threshold Into Segmentation" menu item simply creates a segmentation using all voxels that have a value within the selected range of values. It might be useful for segmenting a subcortical structure. ----------------------------------- John Harwell j...@brainvis.wustl.edu Department of Anatomy and Neurobiology Washington University School of Medicine 660 S.
