title: A survey of current software for genetic power calculations.
abstract: Estimation of power is a key step in any study. This review briefly outlines the factors that affect power and the two main approaches for estimating it. There are a number of web-based tools and programs freely available to enable geneticists to perform power calculations, and the specifics of some of these are discussed here.
