Public Member Functions
	Label ()
	Default constructor for a label.
	Label (std::vector< int > vertices, std::vector< float > values)
	Construct a Label from the given vertices / voxel numbers and values.
	Label (std::vector< int > vertices)
	Construct a Label from the given vertices / voxel numbers.
std::vector< bool >	vert_in_label (size_t surface_num_verts) const
	Compute for each vertex of the surface whether it is inside the label.
size_t	num_entries () const
	Return the number of entries (vertices/voxels) in this label.

Public Attributes
std::vector< int >	vertex
	vertex indices for the data in this label if it is a surface label. These are indices into the vertices of a surface mesh to which this label belongs.
std::vector< float >	coord_x
	x coordinates of the vertices in case of a surface label, or voxels coordinates for a volume label.
std::vector< float >	coord_y
	y coordinates of the vertices in case of a surface label, or voxels coordinates for a volume label.
std::vector< float >	coord_z
	z coordinates of the vertices in case of a surface label, or voxels coordinates for a volume label.
std::vector< float >	value
	the value of the label, can represent continuous data like a p-value, or sometimes simply 1.0 or 0.0 (interpreted as int/bool) to mark vertices inside/outside of a certain area.

Detailed Description

Models a FreeSurfer label. Can be a surface or volume label. A label contains entries for a subset of the vertices of a mesh (or the voxels of a volume). For a surface label, the 'vertex' field contains a vertex index, the coord_* fields may contain the vertex coordinates, and the value field may contain some per-vertex descriptor or analysis result, like a p-value. For a volume label, the 'vertex' field contains a running number, the coord_* fields contain (as floats) the voxel R,A,S indices, and the value field may contain some per-voxel descriptor or analysis result, like a p-value. Note: The variable names herre assume this is a surface label, do not let that confuse you when working with volume labels.
