| Open AccessTracing cancer evolution and heterogeneity using Hi-C
It is challenging to analyse chromosomal rearrangements in heterogeneous solid cancers. Here the authors present HiDENSEC, a method to jointly infer absolute copy number, ploidy, tumor purity and large-scale rearrangements from Hi-C data. The increased statistical power afforded by joint inference enables novel insights into cancer genome evolution.
