gwasPipeline

Scripts to process genotype data:

  • Preprocessing
  • Imputation

Installation

Basic:

git clone --recursive https://github.com/jodyphelan/gwasPipeline.git
cd gwasPipeline
bash install_prerequisites.sh

If you want to use 1000 Genomes reference panels for imputation:

bash download_1kg.sh 4

Where 4 can be replaced with the number of threads available.

Usage

If you have a plink formatted bim/bed/fam dataset e.g. data.bim data.bed data.fam:

/path/to/preprocessGWAS.py config /path/to/data
/path/to/preprocessGWAS.py init config.txt

This will use the 1KG data downloaded earlier and perform all the steps required before imputation. This can then be followed by imputation:

/path/to/preprocessGWAS.py impute final.preimpute <chromosome> <threads>
