Overview

This module is a Python package containing tool for network analysis of HiC data. It starts from HiC Interaction pairs, then generating network and clustering. Finally ranking all clusters by their interaction change.

System Requirements

Hardware Requirements

This package requires only a standard computer with enough RAM to support the in-memory operations.

Software Requirements

HicHub mainly depends on the Python scientific stack.

python <=3.3
pandas
numpy
pybedtools
python-igraph
scipy

If you want to convert .hic to input file faster, please install strawC. Detail: https://github.com/aidenlab/straw

Installation Guide

Recommend to use bioconda for installing. Create the environment from the environment_hichub.yml file:

conda env create -f environment_hichub.yml
python3 -m pip install hichub --user
python3 -m pip install numpy pandas pybedtools python-igraph scipy

https://bioconda.github.io/user/install.html

Or

Example of Running (Demo)

Input Format: HiC Interaction in txt format. Example of test data can be found in ~/test_data %% Convert .hic to required input format python convert_hic_to_pair.py -i ~/ -n NONE -f test.hic -r 10000

#chr	bin1	bin2	Cond1	Cond2
10	3000000	3010000	100	200

EXAMPLE:

%% Find hub by shrinked algorithm
callhub.py -i chr10_test.bed -f WT_na -b DKO_na -r 10000 -d 0.5
or (if callhub.py was not found in your path, please download this git and ./bin/callhub.py )
python3 ./bin/callhub.py -i chr10_WT_na-DKO_na.bed -f WT_na -b DKO_na -r 10000 -d 0.5

Options:

  -h, --help            show this help message and exit
  -i <file>, --in=<file>
                        Path to Input HiC file in txt format
  -f <str>, --foreground_name=<str>
                        Name of condition as foreground.
  -b <str>, --background_name=<str>
                        Name of condition as background.
  -r <int>, --resolution=<int>
                        Resolution of HiC txt
  -d <float>, --filtered_density=<float>
                        Density cutoff for hub shriking.

Output of Hubs:

0	1	2	hub_name	Num_vertices	pvalue
chr10	20930000	21060000	chr10:20930000-21060000	11	7.88966007260005e-09
chr10	19590000	19720000	chr10:19590000-19720000	11	7.809766623341443e-05
chr10	80210000	80340000	chr10:80210000-80340000	11	9.520611432439225e-05

Collect HiC Interaction in txt format, rank interaction change Hub. Input
Format should be: #chr        bin1    bin2    Cond1   Cond2

  -b <str>, --background_name=<str>
                        Name of condition as background.
  -r <int>, --resolution=<int>
                        Resolution of HiC txt
  -t <int>, --num_threads=<int>
                        Num_threads
