eigensoft - 7.2.1+dfsg-1 main

The EIGENSOFT package combines functionality from the group's population
genetics methods (Patterson et al. 2006) and their EIGENSTRAT stratification
method (Price et al. 2006). The EIGENSTRAT method uses principal components
analysis to explicitly model ancestry differences between cases and
controls along continuous axes of variation; the resulting correction is
specific to a candidate marker's variation in frequency across ancestral
populations, minimizing spurious associations while maximizing power to
detect true associations. The EIGENSOFT package has a built-in plotting
script and supports multiple file formats and quantitative phenotypes.
