Genomic Data Analysis for Beginners

Learn genomic data analysis fundamentals through this comprehensive tutorial series designed specifically for beginners working with single nucleotide polymorphism (SNP) data. Master the theoretical foundations of SNPs and their practical applications in genomics research, starting with an understanding of what SNPs are and how they function in genetic analysis. Explore genomic data file formats and structures commonly used in SNP analysis, gaining familiarity with the organization and interpretation of genotype data. Get hands-on experience with PLINK, a powerful command-line tool for genomic data analysis, learning how to initiate and navigate this essential software. Develop proficiency in R and RStudio for statistical analysis and data visualization in genomics contexts. Practice converting between different genotype data formats using PLINK to ensure compatibility across various analysis platforms. Implement quality control procedures for SNP datasets, learning to identify and filter out problematic markers and samples that could compromise analysis results. Conduct principal component analysis (PCA) on SNP data to explore population structure and genetic relationships within datasets. Apply simple PCA analysis techniques using PLINK to visualize genetic variation patterns and population stratification, with accompanying written resources available through the Genomics Boot Camp book for additional reference and deeper understanding.
