    Analysis of Chromosome Conformation Capture data (Hi-C).

    Build Status Nextflow

    install with bioconda Docker Singularity Container available

    Introduction

    This pipeline is based on the HiC-Pro workflow. It was designed to process Hi-C data from raw FastQ files (paired-end Illumina data) to normalized contact maps. The current version supports most protocols, including digestion protocols as well as protocols that do not require restriction enzymes such as DNase Hi-C. In practice, this workflow was successfully applied to many data-sets including dilution Hi-C, in situ Hi-C, DNase Hi-C, Micro-C, capture-C, capture Hi-C or HiChip data.

    The pipeline is built using Nextflow, a workflow tool to run tasks across multiple compute infrastructures in a very portable manner. It comes with docker / singularity containers making installation trivial and results highly reproducible.

    Pipeline summary

    1. Mapping using a two steps strategy to rescue reads spanning the ligation sites (bowtie2)
    2. Detection of valid interaction products
    3. Duplicates removal
    4. Create genome-wide contact maps at various resolution
    5. Contact maps normalization using the ICE algorithm (iced)
    6. Quality controls and report (MultiQC)
    7. Addition export for visualisation and downstream analysis (cooler)

    Quick Start

    i. Install nextflow

    ii. Install one of docker, singularity or conda

    iii. Download the pipeline and test it on a minimal dataset with a single command

    nextflow run nf-core/hic -profile test,<docker/singularity/conda/institute>

    iv. Start running your own analysis!

    nextflow run nf-core/hic -profile <docker/singularity/conda/institute> --reads '*_R{1,2}.fastq.gz' --genome GRCh37

    See usage docs for all of the available options when running the pipeline.
