Powering genomic analysis, at every scale

An open-source library for scalable genomic data exploration
GWAS with Hail (click to show code)


pip install hail

Hail requires Python 3 and the Java 8 JRE

GNU/Linux wil also need C and C++ standard libraries if not already installed

Detailed instructions


Simplified Analysis

Hail is an open-source Python library that simplifies genomic data analysis. It provides powerful, easy-to-use data science tools that can be used to interrogate even biobank-scale genomic data (e.g UK Biobank, TopMed, FinnGen, and Biobank Japan).

Genomic Dataframes

Modern data science is driven by table-like data structures, often called dataframes (see Pandas). While convenient, they don't capture the structure of genetic data, which has row (variant) and column (genotype) groups. To remedy this, Hail introduces a distributed, dataframe-like structure called MatrixTable.

Input Unification

The Hail MatrixTable unifies a wide range of input formats (e.g. vcf, bgen, plink, tsv, gtf, bed files), and supports scalable queries, even on petabyte-size datasets. By leveraging MatrixTable, Hail provides an integrated, scalable analysis platform for science.
