This program is an implementation in C++ of the method for correcting the winner's curse in genetic association studies published in Genetic Epidemeology (2009): http://www3.interscience.wiley.com/cgi-bin/fulltext/121591995/PDFSTART The winner.exe file can be run in Unix platform directly. The command line will be: ./winner -input input_file_name -alpha > output_file_name Here the input_file_name is the name of your input file; the alpha is the desired significance level; the output_file_name is the file name you'd like the results to be put in. The input file will have 5 columns: column 1: SNP name column 2: sample size for controls column 3: sample size for cases column 4: number of risk alleles in controls column 4: number of risk alleles in cases An example of the input file "sample_input.txt": SNP N0 N1 m0 m1 rs1 100 200 50 150 rs2 120 220 50 120 rs3 200 180 100 120 rs4 200 200 200 240 The header line is required for the input file. The sample output file "sample_output.txt": The significance level = 0.05 The number of SNPs = 4 SNP N0 N1 m0 m1 naive_p naive_d naive_OR as_mle_p as_mle_d as_mle_OR asy_sd_p asy_sd_d asy_sad_OR rs1 100 200 50 150 0.2500 0.1250 1.8000 0.2501 0.1248 1.7981 0.0351 0.0475 0.4228 rs2 120 220 50 120 0.2083 0.0644 1.4250 0.2085 0.0643 1.4244 0.0377 0.0559 0.4510 rs3 200 180 100 120 0.2500 0.0833 1.5000 0.2692 0.0415 1.2239 0.0327 0.0604 0.3596 rs4 200 200 200 240 0.5000 0.1000 1.5000 0.4999 0.1003 1.5016 0.0289 0.0451 0.2768 The first line tells you what significance level you have chosen; the second line is the number of SNPs in the file; the third line is the header for the results. From the fourth line, there are 14 columns: column 1-5 is the same as the input file; column 6-8 is the naive estimator for allele frequency, allele frequency difference between cases and controls, and OR, respetively; column 9-11 is the ascertainment-corrected mle for allele frequency, allele frequency difference between cases and controls, and OR, respetively; column 12-14 is the asymptotic standard deviation (SD) of the ascertainment-corrected mle for allele frequency, allele frequency difference between cases and controls, and OR, respetively.
