	e.g.:		e.g.:
	-36 -66 -10 ~~Fusiform_L~~ 44 -75 -11 ~~Occipital_Inf_R~~ 8.49		-36 -66 -10 Fusiform.L 44 -75 -11 Occipital.Inf.R 8.49
	-42 - 58 -13 ~~Fusiform_L~~ -30 -82 -8 ~~Occipital_Inf_L~~ 3.78		-42 - 58 -13 Fusiform.L -30 -82 -8 Occipital.Inf.L 3.78

			If you're wondering why the labels are delimited with dots instead of the underscores that FreeSurfer label files typically use, it appears that BrainNet Viewer uses the underscore character to indicate that the following character is a subscript, and that makes the labels look a little goofy.

	Connections are between nodes and recorded in an adjacency matrix. If there are N nodes, the adjacency matrix must be N x N.		Connections are between nodes and recorded in an adjacency matrix. If there are N nodes, the adjacency matrix must be N x N.

			==Generating Node and Edge Files==
			The Scripts/Matlab/ folder on ubfs contains a Matlab script, <code>coordsToBrainMap</code> for parsing a table of coordinates and lables of edges and generating corresponding .edge and .node files. As it stands, the script takes as a single parameter the name of a tab-delimited file. The file contents are expected to be organized as follows:
			Xa (double) Ya (double) Za (double) Label_a (string) Xb (double) Yb (double) Zb (double) Label_b (string) weight (double)

			e.g.:
			-36 -66 -10 Fusiform_L 44 -75 -11 Occipital_Inf_R 8.49
			-42 - 58 -13 Fusiform_L -30 -82 -8 Occipital_Inf_L 3.78

+Brain Net Viewer is a handy visualization program for spatially rendering brain networks. The latest version can always be found [https://www.nitrc.org/projects/bnv/ here], and the most recent version (as of September, 2018) can be found in BrainNetViewer_20171031.zip in the UBFS/Software folder.
 ==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, though the files do not use column headers:
