WitrynaHere, we carried out genotype imputation to increase the density of single nucleotide polymorphisms in a large-scale Swine F 2 population using a reference panel including 117 individuals, followed by a series of GWAS analyses. The imputation accuracies reached 0.89 and 0.86 for allelic concordance and correlation, respectively.

WitrynaThis list is part of IMPUTE2 output or could be additional list of SNPs that we wish to exclude for other reasons. In short, filter at the point of analysis not the imputated files. If info file is missing we can run SNPTEST with -summary_stats_only flag, which gives you the info score. Here is an old still relevant post at BioStars post ... WitrynaTo mimic a typical imputation analysis, a pseudo-GWAS dataset was constructed by extracting the CG SNP genotypes at all the sites included on a given array. All sites not on the array were then imputed using the UK10K reference panel 9. Imputation was carried out using IMPUTE2 10 which chooses a custom reference panel for each study http://zarlab.cs.ucla.edu/imputing-phenotypes-for-genome-wide-association-studies/ bitbucket power automate
