This has given me an opportunity to speak with advocates of surface-based manual labeling (parcellation) who make compelling arguments about the relatively easy learning curve and visual evaluation capabilities when working with surfaces. I would appreciate hearing people's opinions regarding the differences between manual labeling of image volumes and surfaces.<br /> <br /> In particular, one person raised a comment about how in the surface representation the concept of the 'dividing plane' would not exist, and would be replaced by some sort of vertex-vertex cuts in the surface view. Does anyone have a position on how to deal with a labeling protocol's dividing planes when labeling brain surfaces?<br /> <br /> cheers,<br /> @rno Arno Klein Tue, 15 Sep 2009 17:19:54 GMT http://www.nitrc.org/forum/forum.php?thread_id=1106&forum_id=1160 http://www.nitrc.org/forum/forum.php?thread_id=1100&forum_id=1160 Welcome to Open-Discussion Christian Haselgrove Mon, 14 Sep 2009 21:12:22 GMT http://www.nitrc.org/forum/forum.php?thread_id=1100&forum_id=1160
