HiC-Pro was designed to process Hi-C data, from raw fastq files (paired-end Illumina data) to the normalized contact maps. Since version 2.7.0, HiC-Pro supports the main Hi-C protocols, including digestion protocols as well as protocols that do not require restriction enzyme such as DNase Hi-C. In practice, HiC-Pro can be used to process dilution Hi-C, in situ Hi-C, DNase Hi-C, Micro-C, capture-C, capture Hi-C or HiChip data.
The pipeline is flexible, scalable and optimized. It can operate either on a single laptop or on a computational cluster. HiC-Pro is sequential and each step of the workflow can be run independantly.
HiC-Pro includes a fast implementatation of the iterative correction method (see the iced python library for more information).
In addition, HiC-Pro can use phasing data to build :ref:`allele specific contact maps <AS>`.

For any question about HiC-Pro, please contact [email protected] or use the HiC-Pro forum !
The HiC-Pro pipeline requires the following dependencies :
- The bowtie2 mapper
- Python (>2.7) with pysam (>=0.8.3), bx(>=0.5.0), numpy(>=1.8.2), and scipy(>=0.15.1) libraries
- R with the RColorBrewer and ggplot2 packages
- g++ compiler
- Samtools (>1.0)
- Unix sort (which support -V option) is required ! For Mac OS user, please install the GNU core utilities !
Bowtie >2.2.2 is strongly recommanded for allele specific analysis.
To install HiC-Pro (>=2.7.8):
tar -zxvf HiC-Pro-master.tar.gz
cd HiC-Pro-master
## Edit config-install.txt file if necessary
make configure
make install
For older version (<2.7.8), the following process can be used
tar -zxvf HiC-Pro-master.tar.gz
cd HiC-Pro-master
## Edit config-install.txt file if necessary
make CONFIG_SYS=config-install.txt install
Note that if some of these dependencies are not installed (i.e. not detected in the $PATH), HiC-Pro will try to install them.
You can also edit the config-install.txt file and manually defined the paths to dependencies.
| SYSTEM CONFIGURATION | |
|---|---|
| PREFIX | Path to installation folder |
| BOWTIE2_PATH | Full path the bowtie2 installation directory |
| SAMTOOLS_PATH | Full path to the samtools installation directory (>0.1.19) |
| R_PATH | Full path to the R installation directory |
| PYTHON_PATH | Full path to the python installation directory (>2.7) |
| CLUSTER_SYS | Scheduler to use for cluster submission. Must be TORQUE, SGE, SLURM or LSF |
In order to process the raw data, HiC-Pro requires three annotation files. Note that the pipeline is provided with some Human and Mouse annotation files. Please be sure that the chromosome names are the same than the ones used in your bowtie indexes !
- A BED file of the restriction fragments after digestion. This file depends both of the restriction enzyme and the reference genome. See the :ref:`FAQ <FAQ>` and the :ref:`HiC-Pro utilities <UTILS>` for details about how to generate this file. A few annotation files are provided with the HiC-Pro sources.

- First have a look at the help message !
HiC-Pro --help
usage : HiC-Pro -i INPUT -o OUTPUT -c CONFIG [-s ANALYSIS_STEP] [-p] [-h] [-v]
Use option -h|--help for more information
HiC-Pro 2.7.0
---------------
OPTIONS
-i|--input INPUT : input data folder; Must contains a folder per sample with input files
-o|--output OUTPUT : output folder
-c|--conf CONFIG : configuration file for Hi-C processing
[-p|--parallel] : if specified run HiC-Pro on a cluster
[-s|--step ANALYSIS_STEP] : run only a subset of the HiC-Pro workflow; if not specified the complete workflow is run
mapping: perform reads alignment
proc_hic: perform Hi-C filtering
quality_checks: run Hi-C quality control plots
build_contact_maps: build raw inter/intrachromosomal contact maps
ice_norm: run ICE normalization on contact maps
[-h|--help]: help
[-v|--version]: version
- Copy and edit the configuration file 'config-hicpro.txt' in your local folder. See the :ref:`manual <MANUAL>` for details about the configuration file
- Put all input files in a rawdata folder. The input files have to be organized with a folder per sample.
- Run HiC-Pro
- On your laptop
MY_INSTALL_PATH/bin/HiC-Pro -i FULL_PATH_TO_RAW_DATA -o FULL_PATH_TO_OUTPUTS -c MY_LOCAL_CONFIG_FILE
- Using a cluster (TORQUE/SGE/SLURM/LSF)
MY_INSTALL_PATH/bin/HiC-Pro -i FULL_PATH_TO_RAW_DATA -o FULL_PATH_TO_OUTPUTS -c MY_LOCAL_CONFIG_FILE -p
You will get the following message :
Please run HiC-Pro in two steps :
1- The following command will launch the parallel workflow through 12 torque jobs:
qsub HiCPro_step1.sh
2- The second command will merge all outputs to generate the contact maps:
qsub HiCPro_step2.sh
Execute the displayed command from the output folder:
qsub HiCPro_step1.sh
774410[].torque.curie.fr
Then wait for the torque mails... :) Once executed succesfully (may take several hours), then type:
qsub HiCPro_step2.sh
The test dataset and associated results are available at https://zerkalo.curie.fr/partage/HiC-Pro/. Small fastq files (2M reads) extracted from the Dixon et al. 2012 paper are available for test.
## Get the data. Will download a test_data folder and a configuration file
wget https://zerkalo.curie.fr/partage/HiC-Pro/HiCPro_testdata.tar.gz && tar -zxvf HiCPro_testdata.tar.gz
## Edit the configuration file and set the path to Human bowtie2 indexes
## Run HiC-Pro
time HICPRO_INSTALL_DIR/bin/HiC-Pro -c config_test_latest.txt -i test_data -o hicpro_latest_test
