Hi Brian, I read in a surface file and it spit out 3 coordinates, do you know if they are RAS and also there is no vertex number with them, so does the vertex number start at zero and count up then?
they are RAS coords. surface vertices go from 0-> nverts matrix(in matlab) will go from 1-> nverts+1
One more quick question. Do I have to read in the hemisphere's separately or is there a surface file that has both of them together (either the orig surface or the smoothwm surface)?
each hemisphere separately
Thanks so much for you help! Sarah
thank you, brian

hi Sarah-
you can you the matlab code in $FREESURFER/matlab to do this. use read_surf.m for this.

Hello,
Does anybody know if there is a file with or a way to obtain a mapping of the vertex number with say the RAS coordinate system. I know when you are in the tksurfer window by using the mouse/cursor you can see each vertex number with the corresponding RAS coordinate, but is there a way to output all the vertex numbers with the cooresponding RAS coordinates to a file or matrix or some such thing.
Thank you very much for any help.
