colsph reads and writes a sphere cluster file, adding a color (label) table and sphere labels. The color is determined by evaluating either a Delphi map or a force-field grid at the sphere center, and comparing that value to the ranges specified in a user-defined range file, which defines ranges for a series of colors. The program prompts for the information it needs:

The range file is the only one that needs explanation. Its format is as follows:

color_name range_min range_max

The spacing between the values does not matter. The color_name can be up to 30 characters in length. The range_min and range_max must be real numbers, and specify the lower and upper ends of the range respectively. There may be up to 100 colors and 200 range statements.
