Witryna20 cze 2016 · In genome-wide association studies (GWAS), investigators identify variants that are significantly associated with the phenotype by collecting and performing statistical tests on genotypes and phenotypes from a set of individuals. Recently, GWAS samples have increased in size to include tens or hundreds of thousands of variants. Witryna29 sty 2015 · It is an algorithm for genotypic imputation that works on phased genotypes and is designed to handle very large reference panels in a more computationally efficient way with no loss of accuracy. This wiki page is designed to give users a detailed step-by-step description on running typical GWAS imputation experiments. Imputation …
