Witryna22 paź 2011 · Genotype imputation is increasingly employed in genome-wide association studies, particularly for integrative and cross-platform analysis. Several imputation algorithms use reference panels with a larger set of genotyped markers to infer genotypes at ungenotyped marker locations. Witryna7 sty 2016 · We present a genotype imputation method that scales to millions of reference samples. The imputation method, based on the Li and Stephens model and implemented in Beagle v.4.1, is parallelized and memory efficient, making it well suited to multi-core computer processors.

WitrynaIn imputation with the Li and Stephens model, we assume that the target haplotype corresponds to an unobserved path through the HMM state space from the ﬁrst marker to the last marker that includesonestateateachmarker.TheHMMandtheobserveddata on the target haplotype determine a probability distribution on the paths. Witrynabased on genotypes at typed markers and information about LD within the region [3,4,5,6,7,8,9,10,11,12]. These methods are particularly useful in the context of failed genotyping and combining data across multiple platforms and recently have been extended to untyped markers using a reference data set [8,10,11]. chi wai martial artsWitryna29 gru 2014 · Two-step outperformed one-step imputation for imputing to 777K.
