Genome Wide Association Studies Using PLINK
INTRODUCTION TO GENOME-WIDE ASSOCIATION STUDIES (GWAS)
... Especially when the data sets are large, some of the steps of a GWAS pipeline can be computationally demanding and might require quite some time to run. We bypass this problem by reducing the size of the data set with ...

Quantifying the mapping precision of genome wide association studies using whole genome sequencing data
... We excluded SNPs with missingness > 0.05, Hardy- Weinberg equilibrium test P value < 1 × 10 –6 , or minor allele count (MAC) < 3 (equivalent to MAF < 0.0003) using PLINK [23]. We chose a MAC thresh- old of ...
