SRAtac

A pipeline for ATAC-seq data analysis built on SRAlign.

Introduction

SRAtac is a Nextflow pipeline for processing ATAC-seq data.

SRAtac is designed to be highly flexible pipeline for ATAC-seq data processing. The goal of this pipeline is to perform end-to-end data processing of ATAC-seq samples with extensive QC at all steps.

Quick start

1. Install Nextflow
2. Install Docker
3. Download SRAtac:

   nextflow pull trev-f/SRAtac
   

4. Run SRAtac in test mode:

   nextflow run trev-f/SRAtac -profile test 
   

5. Run your analysis:

   nextflow run trev-f/SRAtac -profile docker --input <input.csv> --genome <valid genome key>
