How are you mapping the volume? To the PALS atlas or to an individual? On what surface are you trying to view the results? Is it a PALS surface? If so, it will have the number 73730 (the number of nodes) in its name.
You can also load the surface into Caret and then map the volume using Map to Caret instead of Map to Atlas. ----------------------------------- John Harwell j...@brainvis.wustl.edu Department of Anatomy and Neurobiology Washington University School of Medicine 660 S.
