Geneland是一个计算机程序包，它允许利用地理参考的个体多位点基因类型来推断种群的数量和这些种群之间遗传不连续的空间位置。该方法的主要假设是：(I)种群的数量未知，并且所有的值都被认为是先验的相等的概率；(Ii)种群分布在空间域中位置未知的一些多边形并集所给出的区域上；(Iii)假设每个种群内存在Hardy-Weinberg平衡；(Iv)每个种群中的等位基因频率是未知的，并且被视为遵循所谓的Dirichlet模型或Falush模型的随机变量。首先简要介绍了在Geneland中实现的执行推理的不同算法。然后通过对Geneland公司生产的模拟数据集的分析，说明了主要的运行步骤和输出(即种群数量的直方图和种群成员的后验概率图)。
Geneland is a computer package that allows to make use of georeferenced individual multilocus genotypes for the inference of the number of populations and of the spatial location of genetic discontinuities between those populations. Main assumptions of the method are: (i) the number of populations is unknown and all values are considered a priori equally likely, (ii) populations are spread over areas given by a union of some polygons of unknown location in the spatial domain, (iii) Hardy-Weinberg equilibrium is assumed within each population and (iv) allele frequencies in each population are unknown and treated as random variable either following the so-called Dirichlet model or Falush model. Different algorithms implemented in Geneland to perform inferences are first briefly presented. Then major running steps and outputs (i.e. histogram of number of populations and map of posterior probabilities of population membership) are illustrated from the analysis of a simulated data set, which was also produced by Geneland.
