higlass-python 1.0.0rc2

Python bindings for HiGlass

higlass-python 🔎

a fresh python library for higlass built on top of higlass-schema and higlass-widget.

Usage

Note A release candidate for higlass-python v1 is now available on PyPI and can be installed via pip:

pip install --pre higlass-python

import higlass as hg

# Remote data source (tileset)
tileset1 = hg.remote(
    uid="CQMd6V_cRw6iCI_-Unl3PQ",
    server="https://higlass.io/api/v1/",
    name="Rao et al. (2014) GM12878 MboI (allreps) 1kb",
)

# Local tileset
tileset2 = hg.cooler("../data/dataset.mcool")

# Create a `hg.HeatmapTrack` for each tileset
track1 = tileset1.track("heatmap")
track2 = tileset2.track("heatmap")

# Create two independent `hg.View`s, one for each heatmap
view1 = hg.view(track1, width=6)
view2 = hg.view(track2, width=6)

# Lock zoom & location for each `View`
view_lock = hg.lock(view1, view2)

# Concatenate views horizontally and apply synchronization lock
(view1 | view2).locks(view_lock)

Development

higlass-python uses the recommended hatchling build-system, which is convenient to use via the hatch CLI. We recommend installing hatch globally (e.g., via pipx) and running the various commands defined within pyproject.toml. hatch will take care of creating and synchronizing a virtual environment with all dependencies defined in pyproject.toml.

Commands Cheatsheet

All commands are run from the root of the project, from a terminal:

Command	Action
hatch run fix	Format project with black . and apply linting with ruff --fix .
hatch run lint	Lint project with ruff ..
hatch run test	Run unit tests with pytest in latest Python version.
hatch run test:test	Run unit tests with pytest in all target Python versions.
hatch run docs:build	Build the documentation in docs/_build/html.
hatch run docs:serve	Start an dev-server for live editing RST files in docs/.

Note: hatch build and hatch publish are available to build and publish the project to PyPI, but all releases are handled automatically via CI.

Alternatively, you can develop higlass-python by manually creating a virtual environment and managing installation and dependencies with pip. For example, create a virtual environment with conda:

conda create -n higlass python=3.11
conda activate higlass

and install higlass-python in editable mode with all optional dependencies:

pip install -e ".[dev,fuse,docs]"

Our CI checks formatting (black .), linting (ruff .), and tests (pytest).
