nf-gwas is a Nextflow pipeline to run biobank-scale genome-wide association studies (GWAS) analysis. The pipeline automatically performs numerous pre- and post-processing steps, integrates regression modeling from the REGENIE package and currently supports single-variant, gene-based and interaction testing. All modules are structured in sub-workflows which allows to extend te pipeline to other methods and tools in future. nf-gwas includes an extensive reporting functionality that allows to inspect thousands of phenotypes and navigate interactive Manhattan plots directly in the web browser.
The pipeline is tested using the unit-style testing framework nf-test and includes a schema definition to run with Nextflow Tower.
