title: A program for the application of the radial distribution function to cluster analysis in cell biology.
abstract: The radial distribution function g(r) is one measure of spatial pattern commonly used in statistical physics to analyze the structure of liquids and has been used in several cellular systems. The graphs of the radial distribution function present three different functional forms. The first form indicates a random distribution; in the second form the graph is characteristic of the cluster distribution; and the third type is characteristic of substantial order. The Funct-G program uses the coordinates (x,y) of each point on m photographs to calculate the radial distribution function g(r) and produce a histogram to analyze graphically this function and to define the distribution model.
