## What it is
A step-by-step tutorial repository teaching genome-wide association study (GWAS) analysis, including quality control, population stratification, association testing, and polygenic risk score (PRS) analysis. It provides shell and R scripts designed for researchers without prior Unix experience, using freely downloadable genetic data.

## Use cases
- learn how to perform GWAS quality control steps
- understand how to correct for population stratification using 1000 Genomes data
- run association analyses on GWAS data
- learn polygenic risk score (PRS) analysis
- get started with genetic data analysis without Unix experience
- use GWAS analysis scripts as a template for my own data
- learn to use PLINK and R for genomics

## When to choose
- you are a researcher new to GWAS and need a guided, step-by-step walkthrough
- you want educational scripts covering QC through PRS in one place
- you need a template pipeline for analyzing your own genetic data
- you want to learn PLINK and R workflows on a Unix/Linux system

## When to avoid
- you need production-ready, maintained software with a license for clinical use
- you work on Windows without a Unix/Linux environment or server
- you need a polished GUI or interactive tool rather than shell scripts
- you require guaranteed support or updates, as the project is tutorial-oriented
