HIPPIE: A high-throughput identification pipeline for promoter interacting enhancer elements

Abstract

Summary: We implemented a high-throughput identification pipeline for promoter interacting enhancer element to streamline the workflow from mapping raw Hi-C reads, identifying DNA-DNA interacting fragments with high confidence and quality control, detecting histone modifications and DNase hypersensitive enrichments in putative enhancer elements, to ultimately extracting possible intra-and inter-chromosomal enhancer-target gene relationships. Availability and implementation: This software package is designed to run on high-performance computing clusters with Oracle Grid Engine.

The source code and instructions are available at the Wang lab website (http://wanglab.pcbi.upenn.edu/hippie/). It is also provided as an Amazon Machine Image to be used directly on Amazon Cloud with minimal installation.
