pyranges1 1.2.0

GenomicRanges for Python.

pyranges

Introduction

Pyranges is a Python library with a Rust backend for efficient and intuitive manipulation of genomics data, particularly genomic intervals (like genes, genomic features, or reads). The library is optimized for fast querying and manipulation of genomic annotations. It enables intuitive and highly efficient pipelines for genomic analysis.

"Finally ... This was what Python badly needed for years." - Heng Li

Version 1.x

This is version 1.x of pyranges. It is a complete rewrite of the original pyranges library, soon to replace the "default" original one (version 0). If you are a v0 user, check the migration guide in the documentation.

The pyranges documentation, including installation instructions, API, tutorial, and how-to-pages, is available at https://pyranges1.readthedocs.io/

Supporting pyranges

• most importantly, cite pyranges if you use it. It is the main metric funding sources care about.
• use pyranges in Stack Overflow/biostars questions and answers
• star the repo (possibly important for github visibility and as a proxy for project popularity)
