Write vertex coordinates and vertex indices defining faces to a file in GIFTI surface format. For a subject (MRI image pre-processed with FreeSurfer) named 'bert', an example file would be 'bert/surf/lh.white.asc'.
write.fs.surface.gii(filepath, vertex_coords, faces)
string. Full path to the output surface file, should end with '.asc', but that is not enforced.
n x 3 matrix of doubles. Each row defined the x,y,z coords for a vertex.
n x 3 matrix of integers. Each row defined the 3 vertex indices that make up the face. WARNING: Vertex indices should be given in R-style, i.e., the index of the first vertex is 1. However, they will be written in FreeSurfer style, i.e., all indices will have 1 substracted, so that the index of the first vertex will be zero.
string the format that was written. One of "tris" or "quads". Currently only triangular meshes are supported, so always 'tris'.
