ChIPComp Statistical Method for ChIP-seq Data Comparison

This document is a technical report that introduces the ChIPComp package, which is designed for differential binding site analyses based on ChIP-seq datasets. The report outlines the methodology used by ChIPComp, which incorporates control sequencing data into a linear model framework to analyze transcription factor binding and histone modifications across different treatment conditions. The workflow includes detecting binding sites using peak-calling software, merging these sites from replicates, calculating read counts, and performing hypothesis testing on the merged binding sites. The report also provides an example of how to utilize the ChIPComp software, detailing the necessary configuration data frame and design matrix required for analysis. Additionally, it discusses the statistical and computational performance of ChIPComp compared to existing methods, emphasizing its capability to handle multiple datasets effectively. The document concludes with session information relevant to the software environment used for the analysis.
