Hi-C A/B Compartment Analysis

소개

This skill provides a standardized, automated workflow for identifying A/B compartments from Hi-C data in .mcool, .cool, or .hic formats. It guides the user through the entire process, including genome alignment, chromosome renaming, PCA-based compartment score extraction, and the generation of visualization-ready BigWig tracks and interaction saddle plots. By leveraging specialized MCP tools, it ensures a reproducible and normalized analysis pipeline for studying large-scale chromatin organization and spatial genome architecture.
