The output is also tabular, +and includes all of the input data plus the additional columns described below. +(`Dataset missing?`_) + +.. _tabular: ${static_path}/formatHelp.html#tab +.. _Dataset missing?: ${static_path}/formatHelp.html + +----- + +**What it does** + +This tool performs a basic analysis of bi-allelic SNPs in case-control +data, using the R statistical environment and Fisher's exact test to +identify SNPs with a significant difference in the allele frequencies +between the two groups. R's "qvalue" package is used to correct for +multiple testing. + +The input file includes counts for each allele combination (AA aa Aa) +for each group at each SNP position. The assignment of codes (1 2 3) +to these genotypes is arbitrary, as long as it is consistent for both +groups. Any other input columns are ignored in the computation, but +are copied to the output. The output appends eight additional columns, +namely the minimum expected counts of the three genotypes for each +group, the p-value, and the q-value. + +----- + +**Example** + +- input file:: + + chr1 210 211 38 4 15 56 0 1 x + chr1 228 229 55 0 2 56 0 1 x + chr1 230 231 46 0 11 55 0 2 x + chr1 234 235 43 0 14 55 0 2 x + chr1 236 237 55 0 2 13 10 34 x + chr1 437 438 55 0 2 46 0 11 x + chr1 439 440 56 0 1 55 0 2 x + chr1 449 450 56 0 1 13 20 24 x + chr1 518 519 56 0 1 38 4 15 x + +Here the group 1 genotype counts are in columns 4 - 6, while those +for group 2 are in columns 7 - 9. + +Note that the "x" column has no meaning. It was added to this example +to show that extra columns can be included, and to make it easier +to see where the new columns are appended in the output. + +- output file:: + + chr1 210 211 38 4 15 56 0 1 x 47 2 8 47 2 8 1.50219088598917e-05 6.32501425679652e-06 + chr1 228 229 55 0 2 56 0 1 x 55.5 0 1.5 55.5 0 1.5 1 0.210526315789474 + chr1 230 231 46 0 11 55 0 2 x 50.5 0 6.5 50.5 0 6.5 0.0155644201009862 0.00409590002657532 + chr1 234 235 43 0 14 55 0 2 x 49 0 8 49 0 8 0.00210854461554067 0.000739840215979182 + chr1 236 237 55 0 2 13 10 34 x 34 5 18 34 5 18 6.14613878554783e-17 4.31307984950725e-17 + chr1 437 438 55 0 2 46 0 11 x 50.5 0 6.5 50.5 0 6.5 0.0155644201009862 0.00409590002657532 + chr1 439 440 56 0 1 55 0 2 x 55.5 0 1.5 55.5 0 1.5 1 0.210526315789474 + chr1 449 450 56 0 1 13 20 24 x 34.5 10 12.5 34.5 10 12.5 2.25757007974134e-18 2.37638955762246e-18 + chr1 518 519 56 0 1 38 4 15 x 47 2 8 47 2 8 1.50219088598917e-05 6.32501425679652e-06 + + </help> +</tool>
