Visual Guide to Genome Wide Association and Interaction Analyses using PLINK and R

In this post, we present a visual approach for exploring genotypic data and performing genome-wide association and epistasis analysis using a simulated phenotype for the YRI (Yoruba in Ibadan, Nigeria) cohort from the International HapMap project. We start first with quality control process for SNPs and samples. 1. Quality Control Data for genome-wide association andContinue reading “Visual Guide to Genome Wide Association and Interaction Analyses using PLINK and R”
