Arlequin provides the average user in population genetics with quite a large set of basic methods and statistical tests, in order to extract information on genetic and demographic features of a collection of population samples. The graphical interface is designed to allow users to rapidly select the different analyses they want to perform on their data. One can explore the data, and analyze several times the same data set from different perspectives, with different selected options.
AssociationViewer is a Java application used to display SNPs in a genetic context. Supplementary data (such as genes or LD plots) is downloaded from various public data sources on the fly and saved locally in a cache. Custom data can be added as supplementary tracks.
BayeScan aims at identifying candidate loci under natural selection from genetic data, using differences in allele frequencies between populations. BayeScan is based on the multinomial-Dirichlet model.
FastEpistasis is a high performance tool designed to test for epistasis effects when analysing continuous phenotypes. It computes tests of epistasis for a large number of SNP pairs, and is an efficient parallel extension to the PLINK epistasis module.
Gaussian Mixture Model (GMM) detects copy number variation from the distribution of copy number ratios. From the data, it will fit one component for each of the following copy number states: deletion, copy-neutral, 1 and 2 additional copy; with a constraint on the difference between the mixture means. Then for a given individual, it will determine the probabilities for each copy number state and compute the expected copy number (dosage).
SwissVar is a portal to search variants (polymorphism) in UniProt Knowledgebase (UniProtKB) entries, and gives direct access to manual annotation on the genotype-phenotype relationship of each specific variant based on literature, as well as pre-computed information (such as conservation scores and a list of structural features when available) to help assess the effect of the variant.
