As a computational framework for scHi-C analysis, Higashi has the following features:

• Higashi represents the scHi-C dataset as a hypergraph
  • Each cell and each genomic bin are represented as the cell node and the genomic bin node.
  • Each non-zero entry in the single-cell contact map is modeled as a hyperedge.
  • The read count for each chromatin interaction is used as the attribute of the hyperedge.
• Higashi uses a hypergraph neural network to unveil high-order interaction patterns within this constructed hypergraph.
• Higashi can produce the embeddings for the scHi-C for downstream analysis.
• Higashi can impute single-cell Hi-C contact maps, enabling detailed characterization of 3D genome features such as TAD-like domain boundaries and A/B compartment scores at single-cell resolution.

We now have Fast-Higashi on conda. conda install -c ruochiz fasthigashi

The conda support for Higashi is still an on-going effort. Currently, you can install it by:

git clone https://github.com/ma-compbio/Higashi/
cd Higashi
python setup.py install

It is recommended to have pytorch installed (with CUDA support when applicable) after installing higashi / fast-higashi.

Please see the wiki for extensive documentation and example tutorials.

Higashi is constantly being updated, see change log for the updating history
