Detecting higher-order structural changes from 3D genome organization data

Three-dimensional (3D) genome organization, which determines how the DNA is packaged inside the nucleus, has emerged as a key regulatory mechanism of cellular processes. High-throughput chromosomal conformation capture (Hi-C) technologies have …

GRiNCH: simultaneous smoothing and detection of topological units of genome organization from sparse chromatin contact count matrices with matrix factorization

Here we present GRiNCH, a novel matrix-factorization-based approach for simultaneous TAD discovery and smoothing of contact count matrices from high-throughput 3C data.

Detecting higher-order structural changes in 3D genome organization with multi-task matrix factorization

Three-dimensional (3D) genome organization, or how the DNA is packaged inside the nucleus, has emerged as a key regulatory mechanism of cellular function and malfunction. High-throughput chromosomal conformation capture (Hi-C) technologies have …
