Softwares & packages

FSTAT

FSTAT is a computer package for PCs which estimates and tests gene diversities and differentiation statistics from codominant genetic markers. It computes both Nei and Weir & Cockerham families of estimators of gene diversities and F-statistics, and tests them using randomisation methods. Jackknife and Bootstrap confidence intervals are also provided. The windows version also estimates statistics developed for the stepwise mutation model (Rst and the like) FSTAT is not developped anymore, and has been superseeded with the R package Hierfstat.

HIERFSTAT

hierfstat is a package for R allowing to estimate F-statistics and variance components with the methods of moments for any number of levels in a hierarchy. The package also allows to test the significance of population differentiation using the likelihood ratio G-statistic or the variance components.

quantiNEMO

quantiNEMO is an individual-based, genetically explicit stochastic simulation program. It was developed to investigate the effects of selection, mutation, recombination, and drift on quantitative traits with varying architectures in structured populations connected by migration and located in a heterogeneous habitat. quantiNEMO is highly flexible at various levels: population, selection, trait(s) architecture, genetic map for QTL and/or markers, environment, demography, mating system, etc.

PCAGEN

PCAGEN is a computer package for Windows which performs Principal Component Analysis (PCA) on gene frequency data. Graphical ordinations of samples are provided and graphs can be saved. Using randomizations, the program also tests the significance of total inertia as well as individual axes inertia.

BIASDISP

BIASDISP is now included in FSTAT and Hierfstat.
