The investigation of within-population spatial genetic structure has been an important aspect of population genetics, allowing determination of the major genetic processes that have established the genetic structure within a population by examining relevant population genetic parameters. I have developed a user-friendly Windows software program, the Program for Spatial Autocorrelation for Windows, Delphi version 1.1.1 (PSAwinD), for examining within-population spatial genetic structure. The features of the software are described herein. The software can calculate Moran's I, standard normal deviate (SND), and the number of alleles in common (NAC) with various optional settings. Those indices deal with different hierarchical levels of genetic data. Different levels of investigation provide different kinds of information, and comprehensive analysis gives us a greater chance of obtaining a deeper insight into the genetic processes operating on the studied population. In addition, a demographic perspective is important in spatial genetic studies
