Dear FS experts:

     I am studying the coordinate system in FS. I met a problem that confused me. I run tksurfer:  tksurfer fsaverage lh inflated. Then I chose a point on surface. It showed that the Vertex Index is 80321, and the Vertex RAS is (-38.53  9.05  40.01).  I thought that the Vertex RAS is just obtained from the lh.inflated file. But I run:  mris_info --v 80321 .\fsaverage\surf\lh.inflated. It showed that coordinate is (-18.4  40.8  32.7).
