Nodes
Nodes are read from a tab-delimited ASCII text file with a '.node' file extension (there is nothing else remarkable about these files). These files must have 6 columns:
X (double) Y (double) Z (double) ColorIndex (double) Size (double) Label (char)
e.g.:
-54 -61 7 1 0.5 l.IFG -58 -50 20 1 0.8 -
Notably, the label column cannot be left blank. If there is no appropriate label, use a hyphen character, as in the second row of the example above.
Connections
Connections are between nodes and recorded in an adjacency matrix. If there are N nodes, the adjacency matrix must be N x N.
