Witryna19 cze 2012 · A method and software package for phasing and imputation was developed for pedigreed populations and resulted in much better accuracies of imputed genotypes than IMPUTE2. The proposed method is fast, accurate, is robust to the pedigree structure of the genotyped animals, and can scale to large datasets. Witryna15 lis 2024 · As the files originate from Impute2 there might be some subtle differences. (3) I would also update Plink version. From the code it seems that you are using either version 1.07 or 1.09. 1.x versions cannot represent probabilities and will make hard-calls so your lose a lot of information because of that. Plink 2.0 can utilize the probabilities ...
WitrynaThis study compares methods of imputing genetic markers, given a typed GWAS scaffold from the Long Life Family Study (LLFS) and latest reference panel of 1000-Genomes.

IMPUTE version 2 (also known as IMPUTE2) is a genotype imputation and haplotype phasing program based on ideas from Howie et al. 2009 [1]. IMPUTE2 is a computer program for phasing observed genotypes and imputing missing genotypes. Most people use just a couple of the program's basic functions, but we have also built …
