Version Compatibility

Reference examples tested with: cooler 0.9+, cooltools 0.6+, matplotlib 3.8+, numpy 1.26+, pandas 2.2+

Before using code patterns, verify installed versions match. If versions differ:

• Python: pip show <package> then help(module.function) to check signatures
• CLI: <tool> --version then <tool> --help to confirm flags

If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.

Hi-C Visualization

"Plot my Hi-C contact matrix" → Create triangle heatmaps, virtual 4C profiles, and multi-track figures combining contact maps with genomic annotations.

• Python: matplotlib.pyplot.imshow() on cooler matrices, cooltools for aggregate plots
• CLI: hicPlotMatrix (HiCExplorer)

Visualize Hi-C contact matrices and genomic features.
