Create igraph undirected graph from a brain surface mesh. — fs.surface.to.igraph • fsbrain

Create igraph undirected graph from a brain surface mesh.

Usage

fs.surface.to.igraph(surface)

Arguments

surface: an fs.surface instance as returned by subject.surface, an existing igraph (which will be returned as-is) or a string which is interpreted as a path to a surface file.

Value

igraph::graph instance

Examples

if (FALSE) { # \dontrun{
  # Find the one-ring neighbors of vertex 15 on the fsaverage left hemi:
  sf = subject.surface(fsaverage.path(T), "fsaverage", "white", "lh");
  g = fs.surface.to.igraph(sf);
  igraph::neighborhood(g, order = 1, nodes = 15);
} # }
