[caret-users] info on normail vectors and their locations

[John Harwell]

Hello,


1) Save the inflated surface as a VTK surface file.  Search the VTK  
surface file for "POINTS" and "NORMALS".

2) Display the Inflated surface in the Main Window.  Select Attributes  
Menu->Vectors->Create Vectors from Surface Normals.  Save the Surface  
Vectors File in ASCII format which will contain the normal vectors.   
Save the inflated coordinate file in ASCII format to the get  
coordinates (XYZ).
