Dear all, I wrote my own function to show the 3D surfaces in Matlab, works splendidly. I now however want to be able to point out Tailarach/MNI coordinates on the 3D surface. I however only have the x, y, z format that is saved in the asc files, which is just where a certex is located in space, with no relation to the original brain whatsoever. The only thing I can retrieve is the vertex index (because that's in the asc file).
How can convert the 3D X, Y, Z values (the same values you get in the console if you click on a point on the surface in tksurfer) to either Vertex RAS/Talairach or Volume index? I read the information on conversions between surface Talairach and Volume Index, that works, but this case is different: I am actually referring to the 3D locations of the vertices. Hopefully someone can help me, thanks a lot in advance, best, Frank _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
