Welcome to Genome-Analysis-Tutorial Page

Please visit this site to see web version of this git repository.
https://kennethjhan.github.io/Genome-Analysis-Tutorial/

This page will help you to learn how to make pipeline based on GATK BestPractice.

From this page, https://kennethjhan.github.io/Genome-Analysis-Tutorial/resource you can download resorce file such as reference fasta, samtools, bwa, picard, GATK4, snpEff and raw fastq file.

YES! This tutorial is based on GATK4 which is latest tool from Broad Institute.

I hope everyone learns how to analyze gene data and contributes scientific field.
