About

hichipper is an open-source command-line toolkit that performs restriction fragment bias-aware preprocessing of HiChIP data. This package takes output from a HiC-Pro run and a sample manifest file (.yaml) that coordinates optional high-quality peaks (identified through ChIP-Seq) and restriction fragment locations as input and produces output that can be used to 1) determine library quality, 2) identify and characterize DNA loops and 3) interactively visualize loops. Loops are assigned strength and confidence metrics that can be used to evaluate samples individually or for differential analysis in downstream tools.
