Learn end-to-end variant calling using Linux and R: From Raw NGS data to variants with visualization and interpretation
What you'll learn
Understand the fundamentals of variant calling and its role in NGS data analysis.
Set up a Linux environment for bioinformatics using Windows or native systems.
Perform quality control and trimming of raw FASTQ sequencing data.
Align sequencing reads to a reference genome using industry-standard tools.
Use Samtools and FreeBayes to call SNPs and indels from aligned reads.
Filter and refine variant calls to ensure accuracy and reliability.
Visualize genomic variants using IGV (Integrative Genomics Viewer).
Analyze and interpret VCF files using R and essential bioinformatics packages.
Automate parts of the variant calling pipeline with shell scripting.
Gain hands-on experience with real NGS datasets and submit results as assignments.
Requirements
No prior programming or bioinformatics experience is required — this course is beginner-friendly.
A computer (Windows, macOS, or Linux) with at least 8GB RAM is recommended for smoother processing.
Stable internet connection for downloading tools and datasets.
Willingness to learn basic Linux commands (we'll cover them step-by-step).
Interest in genomics, DNA sequencing, or data analysis.
