Surfractal

Surfractal calculates fractal atomic density at the points in the probefile based on the atomic density arising from atom centers in the datafile. ASCII input files are a datafile containing atomic coordinates and a probefile providing surface point coordinates. The following list shows the fractal atomic density ranges and corresponding colors in the image.

	Bin #     Value Range        # of Surface Points  color
  	1          <   1.900               3964 	   red
  	2      >=   1.900 <   2.000        2337 	   yellow
  	3      >=   2.000 <   2.100        2504 	   green
  	4      >=   2.100 <   2.200        2123 	   blue
  	5          >=  2.200               1588 	   cobalt
