read_surface

Synopsis

Reads surfaces (source code).

Usage

surf_out = read_surface(file);

• file: File to read from.
• surf_out: Output surface.

Description

Reads surfaces from the disk. Accepted formats are gifti files (provided the gifti library is installed), freesurfer files, .mat files and .obj files.

When provided with a .mat file, the file must contain variables corresponding to a MATLAB surface i.e. ‘vertices’ and ‘faces’ or a SurfStat surface i.e. ‘coord and ‘tri’. ‘vertices’ is an n-by-3 list of vertex coordinates, ‘faces’ is an m-by-3 matrix of triangles, ‘coord’, is a 3-by-n list of vertex coordinates, and ‘tri’ is identical to faces in the MATLAB format.
