Pan-ChIP-seq Analysis of Peak Sets

Project description

PanChIP

PyPI version

Pan-ChIP-seq Analysis of Protein Colocalization Using Peak Sets

The current version of PanChIP supports the hg38 genome assembly.

Prerequisites

Python 3, BEDTools

Installation

pip3 install panchip

Input

PanChIP Analysis: a directory with only 6-column BED files
PanChIP Filter: a 6-column BED file

We recommend most PanChIP users to utilize BED files with constant non-zero fifth column values (e.g., 1, 500, 1000).

Usage

panchip [options]

Commands:
    init            Initialization of the PanChIP library
    analysis        Analysis of a list peak sets
    filter          Filtering library for quality control
Run panchip <command> -h for help on a specific command.

While the design of PanChIP is different from that of BART, we suggest users to also try out the BART software. PanChIP measures the overlap between peak sets, while BART assesses the predictability of profiles based on the library.
