Coolsecture: an easy-to-use and improved framework for cross-species Hi-C contact map comparison

Abstract

Abstract Summary Cross-species Hi-C comparison remains challenging because existing workflows often rely on multiple scripts, heterogeneous I/O formats, and limited diagnostic support. We present coolsecture, a Python 3 command-line toolkit that integrates multiple contact-matrix and synteny formats with bidirectional lift-over and reciprocal consistency assessment, multi-resolution percentile-based comparison, diagnostic visualization, and cross-sample similarity analysis, providing a streamlined and reproducible framework for comparative Hi-C analysis. Availability and implementation coolsecture is distributed under the GPL-3 license.
