Spatial Genetic Software

The concept and the elements of the program have been published at: Degen, B., Petit, R. and Kremer, A. (2001) SGS - Spatial Genetic Software: A computer program for analysis of spatial genetic and phenotypic structures of individuals and populations. Journal of Heredity 92: 447-448.

The program Spatial Genetic Software (SGS) provides an user-friendly WINDOWS tool to analyse small and large scale genetic and phenotypic structures. The program can deal with nearly all types of genetic data such as co-dominant marker (nuclear SNPs, nuclear microsatellites, allozymes), dominant marker (ISSRs, RAPDs, AFLPs) and uniparentally inherited markers (cp- and mt-haplotypes). Most of those data can be analysed on both scales, as individual genotypes of one population (local scale) and as frequencies of alleles or haplotypes for different populations (broad scale). Furthermore, a simple approach to analyse the spatial structure of continuous quantitative traits is integrated The program offers various statistics to analyse the spatial genetic and phenotypic structure in a series of spatial distance classes: Morans's index, Geary's index, number of alleles in common and approaches using genetic distances and FST-values. Further the program can analyse spatial phenotypic data using a simple city-block distance. The statistical significance of all measures is verified by use of permutation test. The results can be stored as csv- or text-files.
