Memory-Optimised Parallel Processing of Hi-C Data [PDF]

open access: yes2015 23rd Euromicro International Conference on Parallel, Distributed, and Network-Based Processing, 2015
This paper presents the optimisation efforts on the creation of a graph-based mapping representation of gene adjacency. The method is based on the Hi-C process, starting from Next Generation Sequencing data, and it analyses a huge amount of static data in order to produce maps for one or more genes.

THUNDER: A reference-free deconvolution method to infer cell type proportions from bulk Hi-C data.

open access: yesPLoS Genetics, 2022
Hi-C data provide population averaged estimates of three-dimensional chromatin contacts across cell types and states in bulk samples. Effective analysis of Hi-C data entails controlling for the potential confounding factor of differential cell type ...

Hi-C analysis: from data generation to integration [PDF]

open access: yesBiophysical Reviews, 2018
In the epigenetics field, large-scale functional genomics datasets of ever-increasing size and complexity have been produced using experimental techniques based on high-throughput sequencing. In particular, the study of the 3D organization of chromatin has raised increasing interest, thanks to the development of advanced experimental techniques.

Effective normalization for copy number variation in Hi-C data

open access: yesBMC Bioinformatics, 2018
Background Normalization is essential to ensure accurate analysis and proper interpretation of sequencing data, and chromosome conformation capture data such as Hi-C have particular challenges. Although several methods have been proposed, the most widely

HiC-GNN: A generalizable model for 3D chromosome reconstruction using graph convolutional neural networks

open access: yesComputational and Structural Biotechnology Journal, 2023
Chromosome conformation capture (3 C) is a method of measuring chromosome topology in terms of loci interaction. The Hi-C method is a derivative of 3 C that allows for genome-wide quantification of chromosome interaction.

DeepHiC: A generative adversarial network for enhancing Hi-C data resolution.

open access: yesPLoS Computational Biology, 2020
Hi-C is commonly used to study three-dimensional genome organization. However, due to the high sequencing cost and technical constraints, the resolution of most Hi-C datasets is coarse, resulting in a loss of information and biological interpretability ...

"Mirror reads" in Hi-C data

open access: yesGenomics and Computational Biology, 2017
The detailed analysis of chromatin structure has been enabled due to rapid development of chromosome conformation capture techniques. One of the most popular and widespread variations is high throughput conformation capture, or Hi-C, based on paired-end sequencing.
