Three-dimensional genome organization plays a fundamental role in gene regulation through topologically associating domains (TADs), chromatin loops, and A/B compartments. We present ChromatinConformationEngine, a pure-Python pipeline for Hi-C data analysis.
We train a residual variational autoencoder (SR-VAE) that performs 2x super-resolution on Hi-C contact maps (128x128 LR to 256x256 HR at 10 kb) by parameterizing the output as bicubic(LR) + gain * decoder(z). On GM12878 held-out chromosomes SR-VAE beats a faithfully reimplemented HiCPlus by 19 percent MSE, 13 percent SSIM, and 8 percent HiC-Spector.
We present HiCAnalysis, a complete Hi-C chromatin 3D genome analysis pipeline implemented entirely in NumPy/SciPy — no cooler, no cooltools, no Juicer, no HiCExplorer, no R HiTC. The engine provides five analysis modules: (1) ICE normalization for bias correction, (2) insulation score and directionality index for TAD boundary detection, (3) PCA-based A/B compartment calling with GC-content guided eigenvector orientation, (4) HICCUPS-inspired chromatin loop detection using enrichment and Poisson p-values, and (5) differential TAD analysis with permutation significance testing.
