-* PC1 (sometimes PC2) of the correlation matrix was typically used to define A/B compartment. We found Calder demonstrates superior robustness over PC-based approach in identifying meaningful compartments, particularly when faced with complex chromosomal structural variations (figure on the left) and loose interaction between the p and q arms (figure on the right)
