Power Atlas

The Power Atlas is a web-based resource to assist investigators in the planning and design of microarray and expression based experiments. This software is currently aimed at estimating the power and sample size for a two group comparison based upon pilot data. The methods underlying the web site are reported in Gadbury et al (2004) and the software is described in further detail at Page et al (2006). There are two ways to use the Power Atlas: 1. We have downloaded the datasets currently in the Gene Expression Omnibus (GEO) and processed each of them with our power analysis software. Investigators may search among the datasets for the experiment that most closely resembles their proposed project and get sample size and power estimates. 2. Investigators may upload their own preliminary data and the program will extrapolate power from this dataset.
