GATK4 Best Practice Nextflow Pipeline

GATK4 Best Practice Nextflow Pipeline is a variant calling pipeline for human whole genome sequencing based on the GATK best practice.

Requirements

Running the pipeline

There is no need to download the code explicitly. Nextflow seamlessly intergrates with GitHub with the following command.

nextflow run oliverSI/GATK4_Best_Practice --fastq1 read_R1.fastq.gz --fastq2 read_R2.fastq.gz
