RAS coordinates, subject A to subject B, C, D etc. - Freesurfer

16 Aug 2004

      Dear Doug et al.,
We have selected a few vertex coordinates in subject-A and noted down the RAS 
coordinates into a file.  We want to get the closest vertices in a group of 
subjects to these vertices from subject-A, using the freesurfer spherical 
registration transforms.
Looking at mri_surf2surf, it seems that it might do the job.  However, the 
vertex RAS coodinates for subject-A are just recorded in an ascii text file with 
rows of XYZ values.  Should we create a dummy .w or .paint file format or is 
there another function that will work with an ascii file of vertex XYZ values in 
the RAS coordinate space?
We have selected only a small set of vertices (about 25 vertices).
Take care, Darren

"People travel to wonder
at the height of the mountains,
at the huge waves of the seas,
at the long courses of the rivers,
at the vast compass of the ocean,
at the circular motion of the stars;
and they pass by themselves without wondering."
--St. Augustine (b. 354, d. 430)
