Geneland (12. April 2011)
Geneland is a computer program whose main goal is to process individual multilocus genetic data to detect population structure, i.e sub-populations at (or close to) Hardy-Weinberg and linkage equilibrium. Although the concept of population refers here to genetic structure only, it is often realistic to assume that populations are spatially organised. Toward this aim, Geneland is based on a spatially explicit model that can make use of both geographic and genetic informations to estimate the number of populations in a dataset and delineate their spatial organisation.
Important areas of application include landscape genetics, conservation genetics, human genetics and epidemiology.
The program is released as an add-on to the free statistical program R and is currently available for Linux, Mac-OS and Windows. It includes a fully clickable user interface requiring no particular knowledge of R.
Assuming that you have data for n individuals genotyped at L loci, the data must be arranged in
