The QuickTest software implements some statistical methods for association testing using uncertain (imputed) genotypes that were published the article "Methods for testing association between uncertain genotypes and quantitative traits" by Kutalik Z*, Johnson T*, Bochud M, Mooser V, Vollenweider P, Waeber G, Waterworth D, Beckmann JS, and Bergmann S in Biostatistics 2010 Jun 11. doi:10.1093/biostatistics/kxq039 pmid:20543033. Some documentation and example files are provided with the source code here. The code was originally written by Toby Johnson and Zoltan Kutalik, in the Computational Biology Group. The Vital-IT computational resource was provided by the Swiss Institute of Bioinformatics. Additional code was added by Alisa Manning and Han Chen at Boston University.
