Hi Joe, that is an overlay for a surface, not a surface itself. It just has a value for each vertex. A surface has geometry and neighborhood info. Try using MRIread.m instead. doug

I've been trying to use the read_surf.m Matlab function included in the Matlab folder of 5.3.0 on a Mac under Matlab 2013a.
[vertex_coords, faces] = read_surf('fmcpr.sm5.fsaverage.lh.nii');
Undefined function or variable "vertex_coords".
Error in read_surf (line 77) vertex_coords = reshape(vertex_coords, 3, vnum)' ;
It looks as though the reason is that the "magic number" evaluates as:
6029568
which does not match either of the numbers it is looking for (which denote triangle and quad files).
Does that mean that current surface files have a different format and this function needs to be updated accordingly?
Anyway, is there some way I can load surface files into Matlab?
I looked through the fsfast Matlab functions but it wasn't clear to me if one of them would do.
The best candidate seemed to be fast_read_curv.m but it yielded too many numbers so I'm thinking a curvature file is something different.
Thanks!
