GITAR (Genome Interaction Tools and Resources) is a standardized, easy to use and flexible solution to manage Hi-C genomic interaction data, from processing to storage and visualization, composed of two modules: HiCtool and a processed data library.
HiCtool (v2.0)
HiCtool is a Python library for processing, normalizing, and visualizing Hi-C data, including topological domain analysis.
Processed data library
Datasets from the 4DN Genome Interaction library processed using a standardized bioinformatic pipeline (HiCtool).
HiCtool v2.0 (03/28/2019)
  • HiCtool code is now hosted on GitHub.
  • Added inter-chromosomal analysis and visualization.
  • Included an additional global normalization method based on a matrix balancing approach.
  • New function to plot the all-by-all chromosomes global contact matrix.
  • Possibility of saving contact matrices in tab separated format.
  • Possibility of plotting topological domains over the heatmaps.
  • Small bug fixes.
GITAR has been published in Genomics, Proteomics & Bioinformatics (see article).
