FIRSTMM-DB contains the following comma separated text files:

n: total number of nodes
m: total number of edges
N: number of graphs


*.link_attrs (m lines; same size as *.edges)
	attributes for the edges in *.edges

*.node_attrs (n lines) 
	matrix of node attributes,
	the comma seperated values in the i-th line is the attribute vector of the node with node_id i

*.node_labels (n lines)
	column vector of node labels,
	the value in the i-th line corresponds to the node with node_id i

*.edges (m lines) 
	sparse (block diagonal) adjacency matrix for all graphs,
	each line corresponds to (row, col) resp. (node_id, node_id)

*.coords (n lines)
	coordinate values for all nodes in the dataset,
	the value in the i-th line is the coordinate of the node with node_id i

*.graph_labels (N lines)
	class labels for all graphs in the dataset,
	the value in the i-th line is the class label of the graph with graph_id i

*.graph_idx (n lines)
	column vector of graph identifiers for all nodes of all graphs,
	the value in the i-th line is the graph_id of the node with node_id i

*.normals (n lines) 
	values for all nodes in the dataset,
	the value in the i-th line is the value of the node with node_id i

*.graph_list (N lines)
	column vector of graph labels,
	the value in the i-th line corresponds to the graph with graph_id i


This folder contains 1 dataset of undirected labeled and attributed graphs for 
graph classification: FIRSTMM-DB.



Node labels:

 1 'bottom'
 2 'middle'
 3 'top'
 4 'handle'
 5 'usable_are'

Node attribute:
  [first dimension]:
  [change in curvature]
	

Edge attributes:
  [first dimension, second dimension]:	
  [distance between points, change in curvature]


Additional information: 

FIRSTMM-DB_graph_list.txt: list of object names 
(each line corresponds to one object in the same order as in graph_labels)

FIRSTMM-DB_coordinates.txt: 3D coordinates

FIRSTMM-DB_normals.txt: 3D normals (unit length); contains NaNs
