Webb26 juni 2024 · Background High levels of pairwise linkage disequilibrium (LD) in single nucleotide polymorphism (SNP) array or whole-genome sequence data may affect both performance and efficiency of genomic prediction models. Thus, this warrants pruning of genotyping data for high LD. We developed an algorithm, named SNPrune, which enables … Webb11 jan. 2024 · The code in coxmeg_gds is very similar to the code in coxmeg_plink, as the latter function converts the plink file to GDS before reading genotypes. coxmeg_gds takes R objects as arguments for phenotypes, covariates, and a connection to the GDS file; while coxmeg_plink takes paths to files on disk. If the user intends to utilize any other ...

Webb17 jan. 2024 · Plink was used to calculate r2 for all pairs of autosomal SNPs called from joint genotyping in the J:ARC samples (425,409) and the J:DO samples (117,429). SNPs that were missing in more than 5% of the samples and that were monomorphic were removed. The 95th percentile of r2 values for SNPs spaced up to 1Mb apart was … Webb5 okt. 2015 · Such structure is commonly envisaged as two interconnected concepts, high relatedness between individuals (determined by the proportion of their genomes identical-by-descent—IBD) and population stratification. The presence of structure is inferred from examining genome-wide genotype data. indian based games
